MIC5282
120VIN, 50mA, Ultra-Low IQ, High-PSRR
Linear Regulator
General Description
Features
The MIC5282 high-performance linear regulator offers a
very-wide input operating voltage range, up to 120V DC,
and supplies an output current of up to 50mA.
Ideal for high input voltage applications such as industrial
and telecom, the MIC5282 offers ±3% initial accuracy,
extremely high-power supply rejection ratio (80dB at
10kHz) and ultra-low quiescent current of 6µA. The
MIC5282 is optimized for high-voltage line transients,
making it ideal for harsh environment applications.
The MIC5282 is offered in both fixed output voltage
(3.3V/5.0V) and adjustable output voltage (1.27V to 5.5V)
options.
The MIC5282 operates over a −40°C to +125°C
temperature range and is available in lead-free, RoHS-
compliant, 8-pin ePad MSOP and 8-pin MSOP packages.
Data sheet and support documentation are found on the
Micrel website: www.micrel.com.

Notes:
1. Exceeding an absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. The maximum allowable power dissipation at any TA (ambient temperature) is PD(max) = (TJ(max) – TA) / θJA. Exceeding the maximum allowable power
dissipation results in excessive die temperature, and causes the regulator to enter thermal shutdown.
4. Devices are ESD sensitive; use proper handling precautions.
5. Specifications are for packaged products only.
6. Assure that VIN ≥ (VOUT + 3V) and VIN ≥ 6V.
7. Quiescent current is specified for the adjustable option. The fixed options will add approximately 1µA due to the internal feedback resistors.
8. Line regulation is a percentage of VOUT.
9. See Typical Characteristics Curve on Pg. 8
