General Description
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.
