MSKSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23
HT7330-A-MS from MSKSEMI, 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, the reference for the regulator. |
| 2 | VIN | power_in | Input pin; the datasheet gives a maximum input voltage of 12 V and recommends placing the input capacitor close to the VIN pin. |
| 3 | VOUT | power_out | Regulated output pin rated for up to 250 mA; the datasheet requires a capacitor greater than 10 µF from output to ground (tantalum recommended) and recommends placing it close to the VOUT pin. |
