# AP7313-12SRG-7

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

AP7313-12SRG-7 from Diodes Incorporated, in a SOT-23R. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Device ground reference return. Connect to system ground with a low-impedance path; place the input and output bypass capacitors close to this pin. |
| 2 | OUT | power_out | Regulated 1.2V voltage output pin, capable of sourcing up to 150mA continuous. Bypass to GND with a 1µF (1µF-4.7µF, X5R/X7R, ESR 10mΩ-200mΩ) ceramic capacitor placed as close as possible to the pin for stability and fast transient response. |
| 3 | IN | power_in | Unregulated voltage input pin, 2V to 6V operating range (7V absolute max). Bypass to GND with at least a 1µF ceramic capacitor located as close as possible to the pin to decouple supply glitches and ensure input stability. |
