1 / 18 page MAQ5281 120VIN, 25mA, Ultra-Low IQ, High-PSRR Linear Regulator Automotive Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 ( 408) 944-0800 • fax + 1 (408) 474-1000 • http://www.micrel.com July 2012 M9999-071112-A General Description The MAQ5281 high-performance linear regulator offers a very-wide input operating voltage range, up to 120V DC, and supplies an output current of up to 25mA. Ideal for high input voltage applications such as automotive, industrial and telecom, the MAQ5281 offers ±3% initial accuracy, extremely high-power supply rejection ratio (>90db) and ultra-low quiescent current of 6µA. The MAQ5281 is optimized for high-voltage line transients, making it ideal for harsh environment applications. The MAQ5281 is offered in both fixed output voltage (3.3V/5.0V) and adjustable output voltage (1.27V to 5.5V) options. The MAQ5281 operates over a 40ºC to +125ºC 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. Features AEC-Q100 qualified Wide input voltage range: 6V to 120V DC Ultra-low quiescent current: 6µA (typ) 25mA guaranteed output current Adjustable output from 1.27V to 5.5V Withstands up to +120V DC at the input Stable with ceramic capacitors Ultra-high PSRR >90dB Ultra-high line transient rejection (load dump) High output accuracy: – ±3% initial accuracy Thermal-shutdown and current-limit protection Thermally-efficient, 8-pin ePad MSOP package Applications Automotive Remote keyless entry power supply Telecom applications ___________________________________________________________________________________________________________ Typical Applications Quiescent Supply Current vs. Input Voltage 0 1 2 3 4 5 6 7 8 9 10 11 12 0 20 406080 100 120 INPUT VOLTAGE (V) VOUT = 5V IOUT = 0 |
