TPS73401DDCR

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

TPS73401DDCR from Texas Instruments, in a TSOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Input supply voltage; operating range 2.7V to 6.5V.
2 GND power_in Ground; must be tied to GND.
3 EN input Enable input; driving high turns on the regulator, driving low puts device in shutdown mode.
4 FB input Feedback input to control loop error amplifier for adjustable output voltage setting via external resistor divider.
5 OUT output Regulated output of the regulator; requires minimum 2.0µF ceramic capacitor to ground for stability.
