MAQ5283
120VIN, 150mA, Ultra-Low IQ, High-PSRR
Linear Regulator
Automotive
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.

Case Temperature*: The temperature measurement was taken at the hottest point on the MAQ5283 case mounted on a 2.25-square-inch PCB at an
ambient temperature of 25°C; see the “Thermal Measurements” section. Actual results depend on the size of the PCB, ambient temperature, and
proximity to other heat emitting components.
