TA78L05F

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.
