Diodes Incorporated · Linear Voltage Regulators (LDO) · SOT-25
AP7315-25W5-7 from Diodes Incorporated, in a SOT-25. 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 | VIN | power_in | Power input pin, operating range 1.7V to 5.25V, with a minimum 0.47µF ceramic capacitor recommended to GND. |
| 2 | GND | power_in | Ground pin, which should be connected to the external circuit ground. |
| 3 | EN | input | Enable pin that must be driven high or low and not left floating; high (1.3V to 5.25V) enables the regulator and low (0V to 0.5V) puts it into shutdown. |
| 4 | NC | unconnected | Not connected internally; datasheet recommends connecting it to GND to maximize PCB copper for thermal dissipation. |
| 5 | VOUT | power_out | Power output pin (fixed 2.5V for this -25 version) that needs an output capacitor, 0.47µF in the typical application circuit, for stability. |
