2A Automotive Low-Noise LDO Linear

Regulators

MAX25302A/MAX25302B

General Description

Benefits and Features

The MAX25302A/MAX25302B are 1.7V to 5.5V V , low-

● Delivers Flexible Operating Range

noise linear regulators that delivers up to 2A of output

• 1.7V to 5.5V Input Voltage Range

current with only 5.1μV

of output noise from 10Hz

• 0.6V to 5.0V Programmable Output Voltage

• 2A Maximum Output Current

• 100mV Maximum Dropout at 2A Load

• < 1.5μA Shutdown Supply Current

RMS

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.

• 5.1µV

Output Noise, 10Hz to 100kHz

RMS

• 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

• -40°C to +125°C Operating Temperature
