TOSHIBA · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
TA78L05F from TOSHIBA, in a SOT-89-3. 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 5 V output (4.75 to 5.25 V at Tj = 25°C) delivering up to 150 mA max, with COUT = 0.1 μF used in the test conditions. |
| 2 | GND | power_in | Ground pin, also connected to the case (tab). |
| 3 | IN | power_in | Unregulated input voltage, absolute maximum 35 V for the 5 V version, with CIN = 0.33 μF used in the test conditions. |
