Applications Description
Output Voltage Adjustment Like most regulators, RS1117 series regulate output comparing output voltage internally generated reference voltage. adjustable version, VREF available externally 1.25V between VOUT ADJ. voltage ratio formed should conduct 10mA (minimum output load). output voltage given following equation: VOUT =VREF (1+R2/R1) IADJ fixed versions RS1117 series, voltage divider provided internally. Thermal Protection RS1117 series have thermal protection which limits junction temperature 150°C. However, device functionality only guaranteed maximum junction temperature +125°C. power dissipation junction temperature RS1117 packages given PD=(VIN VOUT) IOUT, TJUNCTION=TAMBIENT+(PDxJA), Note: TJUNCTION must exceed 125°C Current Limit Protection RS1117 series protected against overload conditions. Current protection triggered typically 1.5A. Stability Load Regulation RS1117 series require capacitor from VOUT provide compensation feedback internal gain stage. This ensure stability output terminal. Typically, 47uF tantalum 100uF aluminum electrolytic sufficient. Note important that this capacitor does exceed 0.5. output capacitor does have theoretical upper limit increasing value will increase stability. COUT more typical high current regulator design. RS1117 series load regulation limited resistance wire connecting load(RP). adjustable version, best load regulation accomplished when resistor divider(R1) connected directly output RS1117 series. When connected, multiplied divider ratio. fixed output versions, internally connected output ground connected side load negative side sense desired.

Thermal Consideration RS1117 series contain thermal limiting circuitry designed protect itself over-temperature conditions. Even normal load conditions, maximum junction temperature ratings must exceeded. mention thermal protection section, need consider sources thermal resistance between junction ambient. contains junction-to-case, case-to-heat-sink interface heat sink resistance itself. additional heat sink applied externally sometimes. increase maximum power dissipation. example, equivalent junction temperature 300mA output current 115°C without external heat sink. Under same junction temperature operates 500mA with adequate heat sink. Therefore, attach extra heat sink recommended. Junction-to-case thermal resistance specified from junction bottom case directly below die. bonding wires appending paths. former lowest resistance path. Proper mounting required ensure best possible thermal flow this area package heat sink. Thermal compound case-to-heat-sink interface strongly recommended. case devices this series electrically connected output. Therefore, case device must electrically isolated, thermally conductive spacer used, long thermal resistance considered. Protection Diode (The figure shown Regulator with Reverse Diode Protection advanced applications) general operation, RS1117 series don't need protection diodes. From cross-section structure RS1117 series, output connected substrate, input connected well. There parasitic reverse diode between them. handle microsecond surge currents 10A. Even with large output capacitance, very difficult those values surge currents normal operation. Only with high value output capacitors, such 1000uF. with input instantaneously shorted ground, damage occur. crowbar circuit input RS1117 series generate those kinds currents, diode from output input recommended. Normal power supply cycling even plugging unplugging system will generate currents large enough damage.
