APX803-26SRG-7

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

APX803-26SRG-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 RESET output Active-low open-drain reset output that is guaranteed logic low for VCC > 1V and is held low for the reset timeout period (140ms min, 200ms typ) after VCC rises above the threshold.
2 GND power_in Ground pin for the device.
3 VCC power_in Operating voltage input, recommended 1.1V to 5.5V and absolute maximum -0.3V to +6.0V.
