Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25
AP7354-45W5-7 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; the datasheet specifies a 2.0V to 5.5V operating input range (6.0V absolute maximum), with a minimum 0.1µF ceramic input capacitor recommended between VIN and GND. |
| 2 | GND | power_in | Ground; the chip ground must be connected through this GND pin, and the regulator GND should be tied to the external circuit ground. |
| 3 | EN | input | Chip enable that must be driven high or low and must not float; high enables the regulator output, low places it in shutdown, with EN high minimum 1.0V and EN low maximum 0.4V, and 6.0V absolute maximum. |
| 4 | NC | unconnected | No connection on the SOT25 package, as shown as NC in the SOT25 pin assignment drawing; the pin is not listed in the pin description table. |
| 5 | VOUT | power_out | Regulated output voltage of 4.5V for this part, with a guaranteed output current of 150mA; VOUT must not exceed VIN + 0.3V. |
