MAX1735EUK50+T

Analog Devices Inc Maxim Integrated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

MAX1735EUK50+T from Analog Devices Inc Maxim Integrated, in a SOT-23-5. 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 reference for the regulator; the datasheet gives no separate limit for this pin.
2 IN power_in Regulator input supply, which can range from -2.5V to -6.5V; bypass with a 1µF capacitor to GND, and this pin also serves as the heatsink, so solder it to a large PC board pad or power plane.
3 SHDN input Shutdown input: drive to GND to turn the regulator off (input current below 1nA), drive above +1.6V or below -1.6V to enable it, and connect to IN for always-on operation.
4 SET input Dual Mode feedback input: connect to GND for the preset output voltage, or use a resistive divider from OUT to SET to set the output between -1.25V and -5.5V, with a regulation setpoint of -1.25V.
5 OUT power_out Regulator output that supplies up to 200mA in regulation and must be bypassed to GND with a 1µF ceramic capacitor.
