QNH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23
HT36-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; the output capacitor to ground must be larger than 2.2µF. |
| 2 | VOUT | power_out | Regulated 3.6V output (±2%) delivering typically 100mA, with an output capacitor larger than 2.2µF to ground required. |
| 3 | VIN | power_in | Supply input rated for up to 24V (absolute maximum -0.3 to +24V), with the capacitor placed close to the pin. |
