Product Details

The MAX25302A/MAX25302B are 1.7V–5.5V VIN, low-noise linear regulators that delivers up to 2A of output current with only 5.1μVRMS 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 output voltage on MAX25302B can be adjusted to a value in the range of 0.6V to 5.0V by using two external resistors. The MAX25302B also includes an active-high POK signal for trouble-free load startup.

The MAX25302A has nine pin-selectable output voltages: 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.1V, 3.3V, 4.0V, and 5V.

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

The MAX25302A/MAX25302B are offered in a 3mm x 3.5mm, 14-pin TDFN package.
