to 100kHz. The regulator maintains ±1% output accuracy
over a wide input voltage range, requiring only 100mV of
input-to-output headroom at full load. The 1.3mA no-load
supply current is independent of dropout voltage.
● Reduces Noise and Improves Accuracy
• ±1% DC Accuracy over Load, Line, and
Temperature
The output voltage on the MAX25302B can be adjusted
to a value in the range of 0.6V to 5.0V by using two ex-
ternal resistors. The MAX25302B also includes an active-
high POK signal for trouble-free load startup.

• 1.3mA Quiescent Supply Current
• > 70dB PSRR at 10kHz
The MAX25302A has nine pin-selectable output voltages:
1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.1V, 3.3V, 4.0V, and 5V.
● Enables Ease-of-Use and Robust Protection
• Stable with 8μF (min) Output Capacitance
• Programmable Soft-Start Rate
All versions include a programmable output soft-start rate,
output overcurrent, and thermal-overload protection.
• Overcurrent and Overtemperature Protection
• Output-to-Input Reverse-Current Protection
• Power-OK Status Pin
The MAX25302A/MAX25302B are offered in a 3mm x
3.5mm, 14-pin TDFN package.
● Reduces PC Board Area
Applications
● Automotive Electronics
● High-End Audio Systems
● High-Resolution Data-Acquisition Systems
• 3mm x 3.5mm, 14-pin TDFN Package
● AEC-Q100
