MAX25307/MAX25308 Two/Three Output Low-Noise LDO Linear Regulators General Description Benefits and Features The MAX25307/MAX25308 are a two/three output linear 1.7V to 5.5V Input Voltage Range regulator family that deliver up to 600mA on channel 1 Factory Selectable Output Voltage of 0.6V to 3.7875V and up to 300mA on channels 2 and 3 with only 37V in 12.5mV Steps RMS of output noise from 10Hz to 100kHz. These regulators 37V Output Noise, 10Hz to 100kHz RMS maintain 1.25% output accuracy over a wide input volt- 1.95mA (Max) Operating Supply Current age range, requiring only 155mV (max) of input-to-output 70dB PSRR at 10kHz headroom at full load. The 1.95mA maximum no-load sup- 600mA Maximum Output Current (OUT1) ply current is independent of dropout voltage. Each output 300mA Maximum Output Current (OUT2/3) is factory programmable between 0.6V to 3.7875V in 1.25% DC Accuracy Over Load, Line, and 12.5mV steps. No external components are needed ex- Temperature cept for the input, output, and bypass capacitors. Each 155mV (Max) Dropout at I Load (3.3V ) MAX1/2/3 IN output has an independent enable input and RESET out- < 1A Shutdown Supply Current put.
