78L12L

TDSEMIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

78L12L from TDSEMIC, 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 VOUT power_out Regulated fixed output of 12V (12.00V typical, 11.40V to 12.60V over Io=1mA to 40mA), with output current rated up to 100mA.
2 GND power_in Common ground reference pin for the regulator.
3 VIN power_in Unregulated input supply; the datasheet gives an absolute maximum input voltage of 35V for the 12V to 15V versions and tests the 12V output with 14.5V to 27V input.
