AP7383-18W5-7

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

AP7383-18W5-7 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 Supply input voltage, with a recommended operating range of 3.5 V to 30 V and an absolute maximum rating of 33 V.
2 GND power_in Ground reference pin for the regulator.
3 EN input Enable input: logic high requires at least 2.0 V, logic low is 0.4 V maximum, and the EN pin current is typically 1 µA; the device enters standby (ISTD typically 0.01 µA) when EN is off.
4 NC unconnected Not connected for the fixed-output version; the datasheet recommends connecting it to GND to improve PCB copper for thermal dissipation.
5 VOUT power_out Regulated output voltage of 1.8 V for the AP7383-18 version, with 150 mA maximum load and a current limit of at least 150 mA.
