The MAX38902A/B/C/D are low-noise, linear regulators that deliver up to 500mA of output current with only 10.5µVRMS 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 365µA 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 over-current and thermal-overload protection.

The MAX38902A/B are offered in an 8-pin TDFN package, while the MAX38902C/D are offered in a 2 x 3, 0.4mm wafer-level package (WLP).

Product Detail

The MAX38902 evaluation kit (EV kit) evaluates the MAX38902A/B/C/D IC family of low noise linear regulators. The MAX38902 EV kit features two independent circuits to evaluate two different IC packages of the MAX38902A/B/C/D family. Both circuits on the EV kit operate over an input range of 1.7V to 5.5V, and provide any output voltage range of 0.6V to 5.3V. The TDFN circuit evaluates the MAX38902A/B, while the wafer-level package (WLP) circuit evaluates the MAX38902C/D. Each circuit output on the EV kit delivers up to 500mA of current.

The EV kit comes with the MAX38902A-ATA+ and the MAX38902C-ANT+ installed.
