HTC Korea TAEJIN Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3L
TJ7550GF from HTC Korea TAEJIN Tech, in a SOT-89-3L. 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 of the regulator (SOT-89-3L pin 1). |
| 2 | IN | power_in | Input voltage pin; the datasheet rates the operating input supply up to 20 V, with an absolute maximum of 28 V. |
| 3 | OUT | power_out | Regulated output voltage pin, delivering up to 250 mA of load current. |
