TPS77733D

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

TPS77733D 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 Regulator ground connection point.
2 EN input Enable input; TTL high signal shuts down the regulator.
3 IN input Input supply voltage.
4 IN input Input supply voltage.
5 OUT output Regulated output voltage.
6 OUT output Regulated output voltage.
7 FB/NC unconnected No internal connection for fixed-output version; feedback input voltage for adjustable device.
8 RESET output Open-drain power-on reset output with 200-ms delay triggered on output undervoltage condition.
