Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25
AP7343D-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 recommended input voltage range is 1.7V to 5.25V (absolute maximum 6.0V), and a minimum 0.47µF ceramic capacitor should be placed between VIN and GND. |
| 2 | GND | power_in | Ground pin, which should be connected to the external circuit ground with a wide copper trace to reduce trace-impedance voltage drop. |
| 3 | EN | input | Enable pin that must be driven high or low and must not float: high (1.3V to 5.25V) turns the regulator on and low (0V to 0.5V) puts it in shutdown, with an absolute maximum of 6.0V. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated power output with fixed output voltage (0.9V to 3.6V; this AP7343D-33 is the 3.3V option) and a guaranteed output current of 300mA. |
