HT7133S

UMW · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

HT7133S from UMW, in a SOT-23. 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 GND power_in Ground reference for the regulator. Common return for VIN and VOUT bypass capacitors.
2 VIN power_in Unregulated input supply. Absolute maximum 30 V; recommended operation up to 30 V with a 10 µF input bypass capacitor to GND. For 3.3 V output, VIN should be at least ~3.4 V (typical 0.1 V dropout at 1 mA).
3 VOUT power_out Regulated 3.3 V output (±3% tolerance). Supplies up to ~100 mA (typ) with 10 µF output bypass capacitor to GND. Load regulation typ 100 mV over 1-30 mA.
