General Description

The MAX25307/MAX25308 are a two/three output linear

regulator family that deliver up to 600mA on channel 1

of output noise from 10Hz to 100kHz. These regulators

maintain ±1.25% output accuracy over a wide input volt-

age range, requiring only 155mV (max) of input-to-output

headroom at full load. The 1.95mA maximum no-load sup-

ply current is independent of dropout voltage. Each output

is factory programmable between 0.6V to 3.7875V in

12.5mV steps. No external components are needed ex-

cept for the input, output, and bypass capacitors. Each

output has an independent enable input and RESET out-

put.
