MAQ5283 120V , 150mA, Ultra-Low I , High-PSRR IN Q Linear Regulator Automotive General Description Features The MAQ5283 high-performance linear regulator offers a AEC-Q100 qualified very-wide input operating voltage range, up to 120V DC, Wide input voltage range: 6V to 120V DC and supplies an output current of up to 150mA. Ultra-low quiescent current: 8A The MAQ5283 is ideal for high input voltage applications 150mA guaranteed output current such as automotive, industrial, and telecom, because it Adjustable output from 1.23V to 5.5V offers 3% initial accuracy, extremely high power supply rejection ratio (75dB at 10kHz) and an ultra-low quiescent Stable with ceramic capacitors current of 8A. The MAQ5283 is optimized for high-voltage Ultra-high PSRR (75dB at 10kHz) line transients, making it ideal for harsh environment Ultra-high line rejection (load dump) applications. High output accuracy: The MAQ5283 is offered in both fixed output voltage (3.3V 3% initial accuracy or 5.0V) and adjustable output voltage (1.23V to 5.5V) Thermal-shutdown and current-limit protection options. Thermally efficient, 8-pin ePad SOIC package The MAQ5283 operates over a 40C to +125C temperature range and is available in a lead-free, RoHS- Applications compliant, ePad SOIC-8 package.
