HK7350-A

HK · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

HK7350-A from HK, in a SOT-89-3. 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 VSS power_in Ground pin, the common reference for the regulator (SOT89-3/TO-92 pin 1; SOT23-3 pin 1).
2 VIN power_in Regulator input; the datasheet's absolute maximum rating for VIN is 18 V.
3 VOUT power_out Regulated output; the absolute maximum output voltage range is Vss-0.3 V to VIN+0.3 V and output current is rated up to 250 mA.
