MIC5282 120V , 50mA, Ultra-Low I , High-PSRR IN Q Linear Regulator General Description Features The MIC5282 high-performance linear regulator offers a Wide input voltage range: 6V to 120V DC very-wide input operating voltage range, up to 120V DC, Ultra-low quiescent current: 6A and supplies an output current of up to 50mA. 50mA guaranteed output current Ideal for high input voltage applications such as industrial Adjustable output from 1.27V to 5.5V and telecom, the MIC5282 offers 3% initial accuracy, Withstands up to +120V DC at the input extremely high-power supply rejection ratio (80dB at Stable with ceramic capacitors 10kHz) and ultra-low quiescent current of 6A. The MIC5282 is optimized for high-voltage line transients, Ultra-high PSRR (80dB at 10kHz) making it ideal for harsh environment applications. Ultra-high line rejection (load dump) The MIC5282 is offered in both fixed output voltage High output accuracy: (3.3V/5.0V) and adjustable output voltage (1.27V to 5.5V) 3% initial accuracy options. Thermal-shutdown and current-limit protection The MIC5282 operates over a 40C to +125C Thermally-efficient, 8-pin MSOP and 8-pin ePad MSOP temperature range and is available in lead-free, RoHS- packages compliant, 8-pin ePad MSOP and 8-pin MSOP packages.
