MAX40203AUK+T

Analog Devices Inc Maxim Integrated · Power Distribution Switches · SOT-23-5

MAX40203AUK+T from Analog Devices Inc Maxim Integrated, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Supply voltage input and diode anode, operating range 1.2V to 5.5V, source of forward current when enabled.
2 GND power_in Ground reference and power supply return.
3 EN input Active-high enable input with internal weak pullup, accepts 0V to 5.5V regardless of VDD, controls forward current path.
4 N.C. unconnected No connection, not internally connected.
5 OUT output Regulated current output and diode cathode, maximum 1A continuous current in SOT package, internal supply source when VOUT > VDD.
