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 150 mA.
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 (75 dB at
10 kHz) and an ultra-low quiescent current of 8 µA. 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.
