AP7343DQ-33W5-7
Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25
AP7343DQ-33W5-7 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; the datasheet gives a recommended input voltage of 1.7 V to 5.25 V, with an absolute maximum input voltage of 6.0 V. |
| 2 | GND | power_in | Ground pin; the datasheet says the regulator ground pin should be connected to the external circuit ground to reduce voltage drop from trace impedance. |
| 3 | EN | input | Enable input that must be driven high or low and must not float; high (at least 1.3 V) enables the regulator, low (at most 0.5 V) puts it in shutdown, and the absolute maximum EN voltage is 6.0 V. |
| 4 | NC | unconnected | No connect pin, not connected internally; the datasheet recommends connecting it to GND to maximize PCB copper for thermal dissipation. |
| 5 | VOUT | power_out | Regulated power output pin; the device is rated for a guaranteed output current of 300 mA, and the -33 suffix denotes a 3.3 V fixed output. |
