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. |
