# AP7333-25SRG-7

**Diodes Incorporated** · Linear Voltage Regulators (LDO) · SOT-23R

AP7333-25SRG-7 from Diodes Incorporated, in a SOT-23R. 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 | GND | power_in | Ground pin for the regulator; the datasheet gives no further electrical limits for this pin. |
| 2 | OUT | power_out | Voltage output pin that should be bypassed to ground through a 1µF ceramic capacitor. |
| 3 | IN | power_in | Voltage input pin that should be bypassed to ground through at least a 1µF capacitor; the recommended input voltage range is 2V to 6V, with an absolute maximum of 7V. |
