MAX604CSA+

MAX604CSA+ Description

The MAX604CSA+ from Analog Devices Inc./Maxim Integrated is a high-performance, low-dropout (LDO) linear voltage regulator designed for precision power management. It supports an adjustable or fixed output (default: 3.3V) with a wide input voltage range of up to 11.5V and delivers a robust 500mA output current. Housed in an 8-pin SOIC package, this regulator is ideal for space-constrained applications requiring stable voltage regulation. Its 0.82V dropout voltage at 400mA ensures efficient operation even with low input-to-output differentials. The device operates within a 0°C to 70°C temperature range and features a low quiescent current of 35 µA, making it suitable for battery-powered systems.

MAX604CSA+ Features

• Adjustable/Fixed Output: Configurable from 1.25V to 11V (factory-set to 3.3V).
• Low Dropout: 0.82V @ 400mA minimizes power loss.
• High Efficiency: 35 µA quiescent current extends battery life in portable devices.
• Robust Protection: Includes over-current, over-temperature, and reverse-polarity protection.
