MAX1726EUK33+T

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

MAX1726EUK33+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 IN power_in Supply voltage input. Operating range +2.5V to +12V (absolute maximum -14V to +14V referenced to GND). Bypass to GND with a 1µF ceramic capacitor; use 10µF if fast large transients are expected or the source is remote.
2 GND power_in Device ground. Tie to system ground; on the MAX1726 both pin 2 and pin 4 are GND and should be connected together.
3 OUT power_out Regulated 3.3V output (factory-preset for the MAX1726EUK33). Guaranteed 20mA output current with 1.5% accuracy; requires a minimum 1µF output capacitor for stable operation over temperature. Foldback current limit typ. 40mA; short-circuit protected indefinitely.
4 GND power_in Second ground pin on the MAX1726 (fixed-output variant). Connect to system ground together with pin 2. On the adjustable MAX1725 this pin is FB instead - not applicable to the MAX1726EUK33.
5 SHDN input Active-low shutdown input. Drive below VIL = 0.5V to disable the regulator (output pulled to ground, IQ drops from 2µA to 0.7µA); drive above VIH = 2V to enable. Tie SHDN to IN for always-on operation; for reverse-battery protection, drive SHDN through a 100kΩ resistor. Absolute range -0.3V to (VIN + 0.3V).
