MSKSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
HT7250-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 | VSS | power_in | Ground reference pin for the regulator; the pin table names it VSS and the pinout figure labels it GND. |
| 2 | VIN | power_in | Regulator input with an absolute maximum rating of -0.3 V to +15 V, a stated withstand voltage of 10 V, and specified operation at VIN = VOUT + 2 V; a 10 µF tantalum input capacitor is recommended. |
| 3 | VOUT | power_out | Regulated output of 5.0 V for the HT7250-MS with ±2% accuracy and 300 mA maximum output current; it requires at least 10 µF output capacitance with ESR below 0.5 Ω. |
