Additional Details

The MAX38904 is a 1.7V–5.5V V_IN, low-noise linear regulator that delivers up to 2A of output current with only 5.1µV_RMS of output noise from 10Hz to 100kHz. The regulator maintains ±1% output accuracy over a wide input voltage range, requiring only 100mV of input-to-output headroom at full load. The 1.3mA no-load supply current is independent of dropout voltage. The MAX38904A/B/C/D have a 70Ω active discharge feature to quickly discharge output capacitors.

The output voltage on MAX38904B can be adjusted to a value in the range of 0.6V to 5.0V by using two external resistors. The MAX38904B also includes an active-high POK signal for trouble-free load startup.

The MAX38904A 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 wafer-level package (WLP) versions of the MAX38904 are available as C and D variants. The MAX38904C uses external feedback resistors for adjusting the output voltage, while the MAX38904D has factory preset output voltages over the range of 0.7V to 5.0V in 50mV steps.

All versions include a programmable output soft-start rate, output overcurrent, and thermal overload protection.

The MAX38904A/B are offered in a 3mm x 3mm, 14-pin TDFN package, while the MAX38904C/D are available in 5 x 3 bump, 2.2mm x 1.37mm WLP, 0.4mm pitch.
