description
TPS71xx integrated circuits family micropower low-dropout (LDO) voltage regulators. order magnitude reduction dropout voltage quiescent current over conventional performance achieved replacing typical pass transistor with PMOS device.
Because PMOS device behaves low-value resistor, dropout voltage very (maxim output current TPS7150) directly proportional output current (see Figure Additionally, since PMOS pass element voltage-driven device, quiescent current very remains independent output loading (typically over full range output current, mA). These specifications yield significant improvement operating life battery-powered systems. family also features sleep mode; applying high signal (enable) shuts down regulator, reducing quiescent current maximum

Implementation many today's high-performance devices these packages requires special attention power dissipation. Many system-dependent issues such thermal coupling, airflow, added heat sinks convection surfaces, presence other heat-generating components affect power-dissipation limits given component.

LOW-DROPOUT VOLTAGE REGULATORS
SLVSQ92B-NOVEMBER 1994
APPLICATION INFORMATION
TPS71xx series low-dropout (LDO) regulators designed overcome many shortcomings earlier-generation LDOs, while adding features such power-saving shutdown mode power-good indicator. TPS71 family includes three fixed-output voltage regulators: TPS7133 (3.3 TPS7148 (4.85 TPS7150 family also offers adjustable device, TPS7101 (adjustable from 9.75
device operation
TPS71 unlike many other LDOs, features very quiescent currents that remain virtually constant even with varying loads. Conventional regulators pnp-pass element, base current which directly proportional load current through regulator lc/p). Close examination data sheets reveals that those devices typically specified under near no-load conditions; actual operating currents much higher evidenced typical quiescent-current versus load-current curves. TPS71xx uses PMOS transistor pass current; because gate PMOS element voltage driven, operating currents invariable over full load range. TPS71 specifications reflect actual performance under load.
Another pitfall associated with pnp-pass element tendency saturate when device goes into dropout. resulting drop forces increase maintain load. During power this translates large start-up currents. Systems with limited supply current fail start battery-powered systems, means rapid battery discharge when voltage decays below minimum required regulation. TPS71xx quiescent current remains even when regulator drops out, eliminating both problems.
Included TPS71xx family 4.85-V regulator, TPS7148. Designed specifically cellular systems, 4.85-V output, regulated within allows operation within low-end limit systems specified tolerance; therefore, maximum regulated operating lifetime obtained from battery pack before device drops out, adding crucial talk minutes between charges.
TPS71xx family also features shutdown mode that places output high-impedance state (essentially equal feedback-divider resistance) reduces quiescent current under shutdown feature used, should tied ground. Response enable transition quick; regulated output voltage reestablished typically its.
minimum load requirements
TPS71xx family stable even zero load; minimum load required operation, sense-pin connection
SENSE fixed-output devices must connected regulator output proper functioning regulator. Normally, this connection should short possible; however, connection made near critical circuit (remote sense) improve performance that point. Internally, SENSE connects high-impedance wide-bandwidth amplifier through resistor-divider network noise pickup feeds through regulator output. Routing SENSE connection minimize/avoid noise pickup essential. Adding network between SENSE filter noise recommended because cause regulator oscillate.
external capacitor requirements
input capacitor required; however, ceramic bypass capacitor (0.047-pF -fiF) improves load transient response noise rejection TPS71 located more than inches from power supply. higher-capacitance electrolytic capacitor necessary large (hundreds mitliamps) load transients with fast rise times anticipated.

Implementation many today's high-performance devices these packages requires special attention power dissipation.

APPLICATION INFORMATION
TPS71 series low-dropoul (LOO) regulators designed overcome many shortcomings earlier-generation LDOs, while adding features such power-saving shutdown mode power-good indicator. TPS71 family includes three fixecklUtputvoltage regulators: TPS7133 (3.3 TPS7148 (4.85 TPS7150 family also offers adjustable device, TPS71 (adjustable from 9.75
device operation
TPS71xx, unlike many o1her LDOs, fea1ures very quiescent currents that remain virtually constant even with varying loads. Conventional regulators pnp-pass element, base current which directly proportional load current through regulator 'dP). Close examination data sheets reveals that those devices typically specified under near no-load conditions; actual operating currents much higher evidenced typical quiescent-current versus load-currenl CUNes. TPS71xx uses PMOS transistor pass current; because gate PMOS element voltage driven, operating currents invariable over full load range. TPS71xx specifications reflect actual performance under load. Another pitfall associated with pnp-pass element tendency saturate when device goes into dropout. resulting drop forces increase maintain load. During power this translates large start-up currents. Systems with limited supply current fail start battery-powered systems, means rapid battery discharge when voltage decays below minimum required regulation. TPS71xx quiescent current remains even when regulator drops out, eliminating both problems. InCluded TPS71xx family 4.8S-V regulator, TPS7148. Designed specifically cellular systems. 4.85-V output, regulated within allows operation within low-end limit systems specified tolerance; therefore, maximum regulated operating lifetime obtained from battery pack before device drops out, adding crucial talk minutes between charges. TPS71 family also features shutdown mode that places thE! output high-impedance state (essentially equal feedback-dlvider resistance) reduces quiescent current under jlA. shutdown feature used, should tied ground. Response enable transition quick; regulated output voltage reestablished typically p.S.

TPS71xx family stable even zero load; minimum load required operation.

Normally. this connection should short possible; however, connection made near criticel circuit (remote sense) improve performance that point. Internally, SENSE connects high-impedance wide-bandwidlh amplifier through resistor-divider network noise pickup feeds through regulator output. Routing SENSE connection minimize/avoid noise pickup essential. Adding network between SENSE filter noise recommended because cause regulator oscillate.
