TPS77618DR

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

TPS77618DR 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 pin; the datasheet lists it as the device ground and the PowerPAD/tab should be soldered to the ground plane for heat sinking.
2 EN input Negative-polarity enable input; applying a TTL high shuts the regulator down, and EN should be tied to ground if shutdown is not used, with an absolute maximum of +16.5 V.
3 IN power_in Input voltage pin; the absolute maximum input voltage range is -0.3 V to +13.5 V.
4 IN power_in Input voltage pin (second IN pin, internally connected to pin 3); the absolute maximum input voltage range is -0.3 V to +13.5 V.
5 OUT power_out Regulated output voltage; the output requires a capacitor of at least 10 µF with ESR between 50 mΩ and 1.5 Ω connected between OUT and GND.
6 OUT power_out Regulated output voltage (second OUT pin, internally connected to pin 5); the output requires a capacitor of at least 10 µF with ESR between 50 mΩ and 1.5 Ω connected between OUT and GND.
7 FB/NC unconnected Feedback input for the adjustable version only; on the fixed-voltage version (TPS77618) this pin is not internally connected.
8 RESET/PG output On TPS776xx devices this is an open-drain power-good (PG) output that needs a pullup resistor, with a maximum voltage of 16.5 V.
