MIC5280 EVALUATION BOARD

The MIC5280 is a high performance low dropout regulator, offering a very low noise output with a very wide input voltage operating range, from 4.5V to 120V DC input voltage. Ideal for high input voltage applications such as industrial and telecom, the MIC5280 offers 2% initial accuracy, extremely high power supply rejection ratio (PSRR > 80dB) and low ground current (typically 30µA). The MIC5280 can also be put into a zero-off-mode current state, drawing minuscule amount of current when disabled. The MIC5280 has a very wide input voltage range, with DC rated from –24V to +120V. This wide input range of the MIC5280 makes it ideal for harsh environment applications.

Precautions

The evaluation board does not have reverse polarity protection. Applying a negative voltage lower than –24V to the VIN (J1) terminal may damage the device.  The MIC5280 evaluation board is tailored for a 4.5V to 120V input voltage range. The input voltage range should not exceed 120VDC on the input.
