HE9073A30MR

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

HE9073A30MR 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 (Table 2, SOT23-3 package).
2 VIN power_in Power input pin; the datasheet rates input voltage at up to 7 V (Vin max 7 V) and absolute maximum supply voltage at 9 V.
3 VOUT power_out Regulated output pin; output current is rated at 500 mA minimum (Typ 500 mA, Max 600 mA at Vin-Vout=1 V).
