AS78L05ZTR-G1

Diodes Incorporated · Linear Voltage Regulators (LDO) · TO-92

AS78L05ZTR-G1 from Diodes Incorporated, 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 OUTPUT power_out Regulated 5V output (±5% over temperature) delivering up to 100mA, with 0.01µF minimum load capacitance recommended to limit high frequency noise.
2 GND power_in Ground reference for the regulator input and output.
3 INPUT power_in Unregulated input voltage, recommended operating maximum 30V for AS78L05 and absolute maximum 36V.
