TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3L
AS78L05RTR from TECH PUBLIC, 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 | OUT | power_out | Regulated 5V output (Vo 4.8V min to 5.2V max at 25°C), rated for a maximum output current of 0.1A, with a 0.1µF output capacitor in the typical application. |
| 2 | GND | power_in | Ground reference pin, connected to the common return of the input and output capacitors in the typical application. |
| 3 | IN | power_in | Unregulated input voltage with an absolute maximum of 35V, with a 0.33µF input capacitor in the typical application. |
