TA78L12F

TOSHIBA · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

TA78L12F from TOSHIBA, 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 OUT power_out Regulated 12 V output; output current is limited to 0.15 A absolute maximum (Tj = 25°C).
2 GND power_in Ground reference pin; the metal case is also connected to GND.
3 IN power_in Unregulated input; absolute maximum input voltage is 35 V per the ratings table.
