Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPS781330220DDCR from Texas Instruments, in a SOT-23-5. 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 IN power_in Input voltage pin operating from 2.2V to 5.5V requiring 0.1µF to 1.0µF ceramic capacitor to ground for stability.
2 GND power_in Ground reference pin with input and output capacitor grounds tied back to IC ground with minimal impedance.
3 EN input Enable pin (active high) that enables regulator when driven above 1.2V or forces shutdown with 18nA quiescent current when driven below 0.4V.
4 VSET input Voltage select pin that provides 3.3V output when driven below 0.4V and 2.2V output when driven above 1.2V.
5 OUT power_out Regulated output voltage pin (3.3V or 2.2V depending on VSET) requiring 1.0µF minimum ceramic capacitor to ground for stability.
