TP151C33S5

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TP151C33S5 from TECH PUBLIC, in a SOT-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 VIN power_in Supply power input. Absolute maximum 7V. Typical operating range Vout+1V to 8V. Bypass with 1uF ceramic to GND.
2 GND power_in Ground reference for the regulator.
3 CE input Chip Enable pin. Logic-high enables the regulator (VCE typ 1.1V). Drive to GND (Vce=0V) to enter shutdown mode where standby current drops to ~1uA.
4 NC unconnected No connection. Leave floating or tie to GND.
5 VOUT power_out Regulated voltage output. Fixed 3.3V (±2% tolerance) for the -33 option. Rated 500mA typical, 600mA absolute max. Requires 1uF ceramic output capacitor to GND for stability.
