# AP7354D-28W5-7

**Diodes Incorporated** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25

AP7354D-28W5-7 from Diodes Incorporated, in a SOT-25. 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 | VIN | power_in | Power input. Operating range 2.0V to 5.5V (abs max 6.0V). Requires a minimum 0.1µF ceramic decoupling capacitor to GND placed close to the pin. |
| 2 | GND | power_in | Ground reference for the regulator. Must be connected to the external circuit ground with low-impedance trace/plane to minimize voltage drop. |
| 3 | EN | input | Chip enable. Drive high (VIH ≥ 1.0V) to enable the regulator output; drive low (VIL ≤ 0.4V) to place the regulator into shutdown. Must not be left floating; tie to VIN if enable feature is not used. Abs max 6.0V. |
| 4 | NC | unconnected | No connection. Leave floating or tie to a convenient net; not internally bonded on the SOT25 package. |
| 5 | VOUT | power_out | Regulated 2.8V output, ±1% accuracy at 25°C, guaranteed load current up to 150mA. Requires a minimum 0.1µF ceramic output capacitor placed close to the pin. Includes ~35Ω active output discharge (AP7354D variant) that engages when EN is pulled low. |
