TDSEMIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89
HT7125-1 from TDSEMIC, in a SOT-89. 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 SOT-89 pinout diagram shows GND as pin 1, on the left when viewed from the front. |
| 2 | VIN | power_in | Input supply pin, with an absolute supply voltage range of -0.3V to +36V. |
| 3 | VOUT | power_out | Regulated output pin, fixed 2.5V for HT7125-1, with a maximum output current of 100mA. |
