The MAX38903A/B/C/D are a family of low-noise linear regulators that deliver up to 1A of output current with only 7µVRMS of output noise from 10Hz to 100kHz.
These regulators maintain ±1% output accuracy over a wide input voltage range, requiring only 100mV of input-to-output headroom at full load. The 1200µA no-load supply current is independent of dropout voltage.
The MAX38903A has nine pin-selectable output voltages 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.1V, 3.3V, 4.0V, and 5V. The MAX38903B/C output voltage can be adjusted to a value in the range of 0.6V to 5.0V using two external resistors. The MAX38903B also includes an active-high POK signal for trouble-free load startup.
The MAX38903D has factory-preset output voltages over the range of 0.7V to 5V in 50mV steps. All versions include a programmable output soft-start rate, output over-current and thermal overload protection.
The MAX38903A/B are offered in a 10-pin, 3mm x 3mm TDFN package, while the MAX38903C/D are offered in a 9-bump, 0.4mm pitch, 1.4mm x 1.4mm wafer-level package (WLP).
