MAX1857 Datasheet

500ma / Low-dropout / Ripple-rejecting Ldo In Max

Manufacturer: Maxim Integrated (now Analog Devices)

MAX1857 Overview

The MAX1857 low-dropout linear regulator operates from a +2.5V to +5.5V supply and delivers a guaranteed 500mA load current with low 120mV dropout. The high-accuracy (±1%) output voltage is preset at an internally trimmed 4.75V or can be adjusted from 1.25V to 5.0V with an external resistive divider. An internal PMOS pass transistor allows the low 135µA supply current to remain independent of load, making this...
