HE9073A25MR

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

HE9073A25MR from HEERMICR, 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 pin of the regulator; the datasheet lists it as the ground connection with no further electrical limits.
2 VIN power_in Power input pin; the datasheet gives an input voltage maximum of 7 V and an absolute maximum supply voltage of 9 V (-0.3 V to 9 V).
3 VOUT power_out Regulated output pin; the datasheet specifies output voltage tolerance of ±1% and an output current of 500 mA typical (600 mA max) at Vin-Vout = 1 V.
