AP7313-33SRG-7

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23R

AP7313-33SRG-7 from Diodes Incorporated, in a SOT-23R. 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 GND power_in Ground pin for the SOT23R package; the datasheet gives no further limit for this pin.
2 OUT power_out Voltage output pin, which should be bypassed to ground with a 1µF ceramic capacitor, and the output is current-limited to approximately 300mA.
3 IN power_in Voltage input pin, which should be bypassed to ground with at least a 1µF capacitor and operates from 2V to 6V.
