The MAX25300A/MAX25300B are low-noise linear regulators that deliver up to 500mA of output current with only 12μVRMS 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 dropout voltage.

The MAX25300A 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 MAX25300B has a resistor-adjustable output voltage in the 0.6V to 5.3V range. The MAX25300B also includes an active-high POK output.

The MAX25300A/MAX25300B are offered in an 8-pin TDFN package.

Product Details

The MAX25300 evaluation kit (EV kit) evaluates the MAX25300A/MAX25300B IC family of low noise linear regulators. The MAX25300 EV kit features two independent circuits to evaluate two different IC packages. The TDFN circuit evaluates the MAX25300A/MAX25300B. 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. Each circuit output on the EV kit delivers up to 500mA of current. The EV kit comes with the MAX25300AATA/V+ installed.
