HIP6211
Dual Noise MLFOperation HIP6211 ultra-low-noise, low-dropout, lowquiescent current linear regulators designed space-restricted applications. These devices supply loads 300mA. shown Block Diagram, HIP6211 consists highly accurate band core, noise bypass circuit, error amplifier, P-channel pass transistor internal feedback voltage divider. 1.0V band reference connected error amplifier's inverting input. error amplifier compares this reference with feedback voltage amplifies difference. feedback voltage lower than reference voltage, pass transistor gate pulled low. This allows more current pass output increases output voltage. feedback voltage high, pass transistor gate pulled high, allowing less current pass output. output voltage feedback through internal resistor voltage divider connected pin. external bypass capacitor connected reduces noise output. Additional blocks include current limiter, over temperature protection, shutdown logic. Internal P-Channel Pass Transistor HIP6211 feature (typ) P-channel MOSFET pass transistor. This provides several advantages over similar designs using pass transistor, including longer battery life. P-channel MOSFET requires base drive, which considerably reduces quiescent current. PNP-based regulators waste considerable current dropout when pass transistor saturates. They also high base-drive current under heavy loads. HIP6211 does suffer from these problems consume only 200µA quiescent current light load. Current Limit HIP6211 includes current limiter. monitors output current controls pass transistor's gate voltage limit output current under 600mA (typ). output shorted ground indefinite amount time without damaging part. Enable Input HIP6211 features active-high Enable input (EN) that allows on/off control regulator. HIP6211 bias current reduces less than microampere leakage current when shutdown. Enable input TTL/CMOS compatible threshold simple logic interfacing. When `H,' output voltage startup rising time 35us typically 300mA output current. Connect normal operation Under Voltage Lockout When input supply goes (below 2.0V) HIP6211 produces internal UVLO (under voltage lockout) signal that generates fault signal shuts down chip. This mechanism protects chip from producing false logic input supply. Quick Charging Mode HIP6211 quick charge block reference very quickly charging capacitor with very high current when chip comes shut down. This quick charge block stops charging capacitor when reference reaches nominal value then chip switches quick charging mode normal operating mode. Over Temperature Protection Over temperature protection limits total power dissipation HIP6211. When junction temperature exceeds +165°C, thermal sensor signals shutdown logic turns pass transistor. thermal sensor turns pass transistor again after IC's junction temperature drops 20°C, resulting pulsed output during continuous thermal-overload conditions. Thermal-Overload protection design protect HIP6211 event fault condition. continual operation, exceed absolute maximum junction temperature rating +150°C.

Noise Reduction HIP6211, external 0.01µF bypass capacitor between with innovative noise bypass scheme reduces output noises dramatically, exhibiting 100µVrms output voltage noise with Cbyp 0.01µF Cout 1µF. 0.01µF bypass capacitor lowoutput voltage noise. leakage current going into should less than 10nA. Noise, PSRR, Transient Response HIP6211 designed deliver ultra-low noise high PSRR, well dropout quiescent currents battery-powered systems. HIP6211 PSRR 75dB 100Hz 70dB 10kHz (see Power-Supply Rejection Ratio Frequency graph Typical Characteristic). When operating from sources other than batteries, improved supply-noise rejection transient response achieved increasing values input output bypass capacitors, through passive filtering techniques. Typical Characteristics show HIP6211 line load transient responses. Dropout Voltage regulator's minimum dropout voltage determines lowest usable supply voltage. batterypowered systems, this determines useful endof-life battery voltage. Because HIP6211 P-channel MOSFET pass transistor, their dropout voltage function drain-to-source resistance (RDS (on)) multiplied load current (see Typical Characteristics). temperatures below -10°C. With dielectrics, sufficient operating temperatures. graph region stable Cout load current shown Typical Characteristics.
