TPS77518DR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

TPS77518DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference pin for the regulator.
2 EN input Negative-polarity enable input; a TTL high signal shuts the regulator down and reduces quiescent current to 1µA at TJ = +25°C, and EN should be tied to ground if the shutdown feature is not used.
3 IN power_in Input voltage pin; absolute maximum VIN range is -0.3 V to +13.5 V, and a ceramic bypass capacitor of 0.047µF or larger improves transient response when the device is far from the supply.
4 IN power_in Input voltage pin (second IN pin, internally tied to pin 3); absolute maximum VIN range is -0.3 V to +13.5 V.
5 OUT power_out Regulated output voltage; requires an output capacitor from OUT to GND with a minimum of 10µF and ESR between 50mΩ and 1.5Ω.
6 OUT power_out Regulated output voltage (second OUT pin, internally tied to pin 5); same output capacitor requirement applies.
7 FB/NC unconnected Feedback input on adjustable versions only; for the fixed-voltage TPS77518 this pin is not internally connected.
8 RESET/PG output Open-drain RESET output on TPS775xx devices (TPS77518 family) that goes low when the output falls to 92%-98% of nominal, requires a pullup resistor, and has a maximum voltage of 16.5 V.
