# AP7370-50Y-13

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

AP7370-50Y-13 from Diodes Incorporated, in a SOT-89. 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 | VOUT | power_out | Regulated 5.0V output. Requires a 1.0µF ceramic output capacitor to GND for stability. Rated for up to 300mA continuous load (typical current limit ~350mA for VOUT>2.5V). |
| 2 | GND | power_in | Device ground reference. Return path for both VIN and VOUT decoupling capacitors. Typical ground current 1.5µA at no load; up to ~250µA at 300mA load. |
| 3 | VIN | power_in | Unregulated supply input. Recommended operating range 3.2V to 18V (absolute max 20V). Requires a 1.0µF ceramic input capacitor to GND close to the pin. |
