HTCSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252
HT7812ARMZ from HTCSEMI, in a TO-252. 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 | Input | power_in | Unregulated input supply; the absolute maximum input voltage is 35 V for the HT78xx types other than HT7824/HT7827, and the HT7812 operating input range is 14.5 V to 27 V. |
| 2 | GND | power_in | Common ground reference pin; the datasheet gives no separate electrical limit for this pin. |
| 3 | Output | power_out | Regulated output of 12 V nominal for the HT7812 (11.50 V to 12.5 V at TJ = 25 °C, IO = 500 mA), with output current rated up to 1.5 A. |
