General Description

Features

The MAQ5283 high-performance linear regulator offers a

very-wide input operating voltage range, up to 120V DC,

and supplies an output current of up to 150mA.

The MAQ5283 is ideal for high input voltage applications

such as automotive, industrial, and telecom, because it

offers ±3% initial accuracy, extremely high power supply

rejection ratio (75dB at 10kHz) and an ultra-low quiescent

current of 8µA. The MAQ5283 is optimized for high-voltage

line transients, making it ideal for harsh environment

applications.

The MAQ5283 is offered in both fixed output voltage (3.3V

or 5.0V) and adjustable output voltage (1.23V to 5.5V)

options.

The MAQ5283 operates over a −40°C to +125°C

temperature range and is available in a lead-free, RoHS-

compliant, ePad SOIC-8 package.

Data sheet and support documentation are available on

the Micrel website: www.micrel.com.
