MAX25301A/MAX25301B

1A Automotive Low-Noise LDO Linear

Regulator

General Description

Benefits and Features

The MAX25301A/B are low-noise automotive linear reg-

ulators that deliver up to 1A of output current with only

● 1.7V to 5.5V Input Voltage Range

● 0.6V to 5.3V Programmable Output Voltage

7µV

of output noise from 10Hz to 100kHz.

● 7µV

Output Noise, 10Hz to 100kHz

RMS

● 1200µA Operating Supply Current

● 70dB PSRR at 10kHz

● 1A Maximum Output Current

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 sup-

ply current is independent of dropout voltage.

● ±1% DC Accuracy Over Load, Line, and Temperature

● 100mV Maximum Dropout at 1A Load

● <1µA Shutdown Supply Current

● Stable with 4µF(min) Output Capacitance

● Programmable Soft-Start Rate

● Overcurrent and Overtemperature Protection

● Output-to-Input Reverse-Current Protection

● Power-OK Output

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 val-

ue in the range of 0.6V to 5.3V using two external resis-

tors. 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 pro-

tection.

● 3mm x 3mm 10-pin TDFN Package

● AEC-Q100

● -40°C to 125°C Operating Temperature

The MAX25301A/B are offered in a 10-pin TDFN (3mm x

3mm) package.

Ordering Information appears at end of datasheet.

Applications

● Automotive Electronics

● Audio Systems

● High-Resolution Data Acquisition Systems
