HT7830-MS

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

HT7830-MS from MSKSEMI, 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 GND power_in Ground pin; the datasheet gives no further electrical limits for this pin.
2 VIN power_in Regulator input; the DC characteristics give an input voltage range of 3.0 V to 12 V, and the absolute maximum rating for VIN is -0.3 V to +15 V.
3 VOUT power_out Regulated output for the HT7830-MS, which has a 3.0 V output with ±2% voltage accuracy at 1 mA and an output current rating of up to 450 mA.
