# AP2401MP-13

**Diodes Incorporated** · AC-DC Controllers and Regulators · MSOP-8-EP

AP2401MP-13 from Diodes Incorporated, in a MSOP-8-EP. 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. All voltages are referenced to this pin. |
| 2 | IN | power_in | Voltage input pin (2.7 V to 5.5 V). Both IN pins must be tied together externally. Place a 0.1 µF or larger ceramic capacitor from IN to GND as close as possible. |
| 3 | IN | power_in | Voltage input pin (2.7 V to 5.5 V). Both IN pins must be tied together externally. Place a 0.1 µF or larger ceramic capacitor from IN to GND as close as possible. |
| 4 | EN | input | Enable input, active low on AP2401. VIL ≤ 0.8 V asserts enable; VIH ≥ 2 V disables the switch. Leakage <1 µA typical. |
| 5 | FLG | output | Fault flag output. Active-low open-drain that reports over-temperature and over-current with a 7 ms typical deglitch/blanking time. Requires an external pull-up resistor (typical 10 kΩ). FLG is disabled for 7 ms after turn-on. |
| 6 | OUT | power_out | Switched voltage output pin. Both OUT pins must be tied together externally. Typical bulk capacitance ≥120 µF plus 0.1 µF ceramic recommended on output. |
| 7 | OUT | power_out | Switched voltage output pin. Both OUT pins must be tied together externally. Typical bulk capacitance ≥120 µF plus 0.1 µF ceramic recommended on output. |
| 8 | NC | unconnected | No internal connection. Recommended to tie to OUT pins. |
