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.

MIC5282 Functional Characteristics February 12, 2014 8 Revision 1.1 Micrel, Inc. MIC5282 Functional Characteristics (Continued) February 12, 2014 9 Revision 1.1 Micrel, Inc. Detailed Description The MIC5282 voltage regulator accepts a 6V to 120V input and has an ultra-low 6µA typical quiescent current while offering an excellent line transient response and PSRR. These features make it ideal for harsh, noisy environments. All options of the device offer 50mA of output current. The MIC5282YMM and MIC5282YMME offer an adjustable output voltage from 1.27V to 5.5V. The MIC5282-3.3YMME and MIC5282-3.3YMM offer fixed 3.3V outputs and the MIC5282-5.0YMME and MIC52825.0YMM offer fixed 5.0V outputs. The YMME packaged devices feature a heat slug to more effectively remove heat from the die. Applications Information Thermal Protection MIC5282 has internal thermal shutdown to protect it from excessive heating of the die. When the junction temperature exceeds approximately +155°C, the output is disabled and the device begins to cool down. The device turns back on when the junction temperature cools by 15°C. This will result in a cycled output during continuous thermal-overload conditions. Current Limit MIC5282 features output current-limit protection. The output sustains a continuous short circuit to GND without damage to the device, but thermal shutdown often results. MIC5282 Output Voltage Setting For the MIC5282YMME and MIC5282YMM, VOUT is programmed from 1.27V to 5.5V using:  R1  VOUT = VREF ×  + 1 R2   where VREF = 1.27V, and R1 and R2 are shown in the Typical Applications circuit. Thermal Measurements It is always wise to measure an IC’s case temperature to make sure that it is within operating limits, but it is easy to get erroneous results. The standard thermal couple that comes with many voltage meters uses a large wire gauge that behaves like a heat-sink, resulting in artificially low case temperature measurements. Use a thermocouple of 36-gauge wire or smaller, such as the Omega (5SC-TT-K36-36), to minimize the heat-sinking effect. Also, apply thermal compound to maximize heat transfer between the IC and the thermocouple. An infrared thermometer is a recommended alternative. The IR thermometer from Optris has a 1mm spot size, ideal for monitoring small surface mount packages. Also, the optional stand makes it easy to keep the beam on the IC for long periods of time. Input Capacitor Connect a 1.0µF capacitor from VIN to GND. Micrel recommends the C5750X7R2E105M, 1.0µF, 250V capacitor made by TDK. When using a different capacitor, assure that the voltage rating of the capacitor exceeds any potential transient. CPSRR Capacitor Connect a 0.1µF capacitor from CPSRR to GND to maintain high power supply rejection. The voltage rating of the capacitor must be at least 14V. Output Capacitor Connect a 10µF capacitor from VOUT to GND. Assure that the voltage rating of the capacitor exceeds the designed output voltage of the MIC5282.
