MICROCHIP MIC5283YML-T5

The MIC5283 high-performance linear regulator offers a very-wide input operating voltage range, up to 120V DC, and supplies an output current of up to 150mA. Ideal for high input voltage applications such as industrial and telecom, the MIC5283 offers ±3% initial accuracy, extremely high-power supply rejection ratio (75dB at 10kHz) and an ultra-low quiescent current of 8μA. The MIC5283 is optimized for high-voltage line transients, making it ideal for harsh environment applications. The MIC5283 is offered in both fixed output voltage (3.3V or 5.0V) and adjustable output voltage (1.22V to 5.5V) options. The MIC5283 operates over a -40°C to +125°C temperature range and is available in lead-free, RoHS-compliant, ePad SOIC-8 and 3mm x 3mm MLF packages.

The MIC5283 voltage regulator accepts a 6V to 120V input voltage and has an ultra-low 8μA typical quiescent current while offering an excellent line transient response and PSRR. These features make it ideal for harsh, noisy environments. All options offer 150mA of output current. The MIC5283YML and MIC5283YME offer an adjustable output voltage from 1.22V to 5.5V. The MIC5283-3.3YML and MIC5283-3.3YME offer fixed 3.3V outputs and the MIC5283-5.0YML and MIC5283-5.0YME offer fixed 5.0V outputs. The YME packaged devices feature a heat slug to more effectively remove heat from the die.
