QNH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92
HT7530A-1Q from QNH, in a TO-92. 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 reference pin for the regulator. |
| 2 | VIN | power_in | Regulator input pin, rated for a maximum voltage of 24 V (absolute maximum VIN is -0.3 V to +24 V), and a capacitor should be placed close to this pin. |
| 3 | VOUT | power_out | Regulated output pin, which needs a capacitor greater than 2.2 μF to ground (tantalum recommended) and provides up to 100 mA output current for the 3.0 V variant. |
