Description

General part information

MAX25301B Series

The MAX25301A/B are low-noise automotive linear regulators that deliver up to 1A of output current with only 7µVRMSof 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 1200µA no-load supply current is independent of dropout voltage.The MAX25301A 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 MAX25301B output voltage can be adjusted to a value in the range of 0.6V to 5.3V using two external resistors. The MAX25301B also includes an active-high POK signal for trouble-free load startup.All versions include a programmable output soft-start rate as well as output-overcurrent and thermal-overload protection.The MAX25301A/B are offered in a 10-pin TDFN (3mm x 3mm) package.ApplicationsAudio SystemsAutomotive ElectronicsHigh-Resolution Data Acquisition Systems
