MAXIM MAX38902DANT27+

The MAX38902A/B/C/D are low-noise, linear regulators that deliver up to 500 mA of output current with only 12 μV_RMS of output noise from 10 Hz to 100 kHz. These regulators maintain ±1% output accuracy over a wide input voltage range, requiring only 100 mV of input-to-output headroom at full load. The 365 μA no-load supply current is independent of drop-out voltage. The MAX38902A have nine, pin-selectable output voltages 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.1V, 3.3V, 4.0V, and 5V. The MAX38902B/C have a resistor adjustable output voltage in the range of 0.6V to 5.3V. The MAX38902B also includes an active-low POK output. The MAX38902D have factory-preset output voltages ranging from 0.7V to 5V. All versions include a programmable output soft-start rate, output overcurrent and thermal overload protection. The MAX38902A/B are offered in an 8-pin TDFN package, while the MAX38902C/D are offered in a 2×3, 0.4 mm wafer-level package (WLP).
