Description

The MAX8877EUK25-T is a low-noise, low-dropout linear regulator designed to operate in the voltage range of 2.5V to 6.5V. It can deliver a maximum output current of 150mA and offers an improved dropout voltage. The device is pin-compatible with the industry-standard '2982, making it easy to replace existing regulators. It features a typical output noise of 30µVRMS and a dropout voltage of only 165mV at 150mA. The output voltage can be preset to different values ranging from 1.5V to 5.0V in 100mV increments.
