**Diodes Incorporated** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

AP130-18SAG-7 from Diodes Incorporated, in a SOT-23-3. 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 | IN | power_in | Power input; recommended input voltage range is 2.7V to 5.5V (absolute maximum +6V). |
| 2 | OUT | power_out | Regulated output voltage (1.8V for this variant) with up to 300mA output current; requires a minimum 10µF capacitor to ground for stability. |
| 3 | GND | power_in | Ground. |
