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. |
