HMCP1703T-3302E

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

HMCP1703T-3302E from HXY MOSFET, in a SOT-23. 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 Ground.
2 VIN power_in Input supply; withstands up to 18V per the features, with the output regulating for VOUT+1.0V≤VIN≤6V in the line-regulation test.
3 VOUT power_out Regulated output (3.3V for the 33 option), rated for 300mA output current with ±2% accuracy.
