产品详情

The MAX25307/MAX25308 are a two/three output linear regulator family that deliver up to 600mA on channel 1 and up to 300mA on channels 2 and 3 with only 37μV_RMS of output noise from 10Hz to 100kHz. These regulators maintain ±1.25% output accuracy over a wide input voltage range, requiring only 155mV (max) of input-to-output headroom at full load. The 1.95mA maximum no-load supply 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 except for the input, output, and bypass capacitors. Each output has an independent enable input and active-low RESET output.

The MAX25308 EV kit is a fully assembled and tested PCB intended to demonstrate the capability of the MAX25308 LDO regulator. The MAX25308 is a 3-output linear regulator family that delivers up to 600mA on Channel 1 and up to 300mA on channels 2 and 3 with only 37μVRMS of output noise from 10Hz to 100kHz. These regulators maintain ±1.25% output accuracy over a wide input voltage range, requiring only 155mV (max) of inputto- output headroom at full load. The 1.95mA maximum no-load supply 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 except for the input, output, and bypass capacitors. Each output has an independent enable input and active-low RESET output.
