MIC5281 Functional Description Output Voltage Setting The MIC5281 voltage regulator accepts a 6V to 120V input and has an ultra-low 6µA typical quiescent current For the MIC5281YMME and MIC5281YMM, VOUT is while offering an excellent line transient response and programmed from 1.27V to 5.5V using Equation 1: PSRR. These features make it ideal for harsh, noisy environments. All options of the device offer 25mA of output current.

Thermal Measurements Applications Information It is always wise to measure an IC’s case temperature to Thermal Protection make sure that it is within operating limits, but it is easy to MIC5281 has internal thermal shutdown to protect it from get erroneous results. The standard thermal couple that excessive heating of the die. When the junction comes with many voltage meters uses a large wire gauge temperature exceeds approximately +155°C, the output is that behaves like a heat-sink, resulting in artificially low disabled and the device begins to cool down. The device case temperature measurements. Use a thermocouple of turns back on when the junction temperature cools by 36-gauge wire or smaller, such as the Omega (5SC-TT- 15°C. This will result in a cycled output during continuous K-36-36), to minimize the heat-sinking effect. Also, apply thermal-overload conditions. thermal compound to maximize heat transfer between the IC and the thermocouple. Current Limit An infrared thermometer is a recommended alternative. MIC5281 features output current-limit protection. The The IR thermometer from Optris has a 1mm spot size, output sustains a continuous short circuit to GND without ideal for monitoring small surface mount packages. Also, damage to the device, but thermal shutdown often the optional stand makes it easy to keep the beam on the results. 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 MIC5281. October 2, 2014 11 Revision 3.0
