MAQ5282
120VIN, 50mA, Ultra-Low IQ, High-PSRR
Linear Regulator
Automotive
General Description
Features
The MAQ5282 high-performance linear regulator offers a
very-wide input operating voltage range, up to 120V DC,
and supplies an output current of up to 50mA.
Ideal for high input voltage applications such as
automotive, industrial and telecom, the MAQ5282 offers
±3% initial accuracy, extremely high-power supply
rejection ratio (80dB at 10kHz) and ultra-low quiescent
current of 6µA. The MAQ5282 is optimized for high-voltage
line transients, making it ideal for harsh environment
applications.
The MAQ5282 is offered in both fixed output voltage
(3.3V/5.0V) and adjustable output voltage (1.27V to 5.5V)
options.
The MAQ5282 operates over a −40°C to +125°C
temperature range and is available in lead-free, RoHS-
compliant, 8-pin ePad MSOP package. This part is also
AEC-Q100 qualified for automotive applications.
Data sheet and support documentation are found on the
Micrel website: www.micrel.com.
