AS78L15RTR-G1

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

AS78L15RTR-G1 from Diodes Incorporated, 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 OUTPUT power_out Regulated 15V output (AS78L15, 14.4V to 15.6V at 25°C) delivering up to 100mA, with 0.1µF output capacitor used in the test circuit and at least 0.01µF recommended to limit high-frequency noise.
2 GND power_in Ground reference pin for input and output.
3 INPUT power_in Unregulated input voltage, 36V maximum for the AS78L15 (17.5V to 30V specified for regulation), with 0.33µF input capacitor used in the test circuit.
