78L05 TB

YFW · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92

78L05 TB from YFW, in a TO-92. 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 (4.8 V min, 5.2 V max at IO = 1 mA to 40 mA) delivering up to 100 mA, with a 0.1 µF output capacitor used in the test circuit.
2 Gnd power_in Ground reference pin shared by input and output.
3 In power_in Unregulated input voltage, absolute maximum 30 V for the 3.3 V to 10 V output versions, with a 0.33 µF input capacitor used in the test circuit.
