QNH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23
HT50-Q from QNH, 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 (地) of the regulator; the datasheet gives no separate voltage or current limit for this pin, and the absolute maximum VIN rating is -0.3 V to +24 V. |
| 2 | VIN | power_in | Input supply pin with an absolute maximum rating of -0.3 V to +24 V; place the input capacitor (10 µF in the typical application) close to this pin. |
| 3 | VOUT | power_out | Regulated output pin for the HT50 (5.0 V nominal, 4.9 V to 5.1 V, at least 100 mA output current); the datasheet requires an output-to-ground capacitor greater than 2.2 µF, tantalum recommended, placed close to this pin. |
