General Description
Benefits and Features
The MAX25300A/B are low-noise linear regulators that de-
● 1.7V to 5.5V Input Voltage Range
● 0.6V to 5.3V Output Voltage Range
liver up to 500mA of output current with only 12µV
RMS
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 indepen-
dent of dropout voltage.
● 12µV
Output Noise, 10Hz to 100kHz
RMS
● 365µA Operating Supply Current
● 70dB PSRR at 10kHz
● 500mA Maximum Output Current
● ±1% DC Accuracy Over Load, Line, and Temperature
● 100mV (Max) Dropout at 500mA Load (3.6V )
IN
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 range of 0.6V to 5.3V. The MAX25300B also in-
cludes an active-high POK output.
● < 0.1µA Shutdown Supply Current
● Stable with 2µF(Min) Output Capacitance
● Programmable Soft-Start Rate
● Overcurrent and Overtemperature Protection
● Output-to-Input Reversed Current Protection
● POK Output
The MAX25300A/B are offered in an 8-pin TDFN package.
● 2mm x 2mm 8-pin TDFN Package
● AEC-Q100
