regulators maintain ±1% output accuracy over a wide in-
put voltage range, requiring only 100mV of input-to-output
headroom at full load. The 365µA no-load supply current
is independent of dropout voltage.
● 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 0.6V to 5.3V range. The MAX25300B also includes
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
● 2mm x 2mm, 8-Pin TDFN Package
● AEC-Q100
● -40°C to +125°C Operating Temperature
The MAX25300A/MAX25300B are offered in an 8-pin
TDFN package.
Applications
● Automotive Electronics
● Audio Systems
