Overview
The demonstration board can be used to evaluate the MIC59300. The MIC59300, a 3.0A, ultra-high speed, low dropout linear regulator, utilizes a split supply input to regulate low output voltages. It is offered in fixed and adjustable outputs. The adjustable version allows the use of a resistor divider network to adjust the output voltage. An enable pin allows it to be placed in a zero-current off mode state. The evaluation board accommodates the adjustable version.

N/A
The MIC59300 requires two power supplies. One to provide a minimum of 3.0A to the VIN and the other to provide Vbias current. Although typical Vbias current is 30mA, in dropout conditions Vbias currents can be very high. A 1A minimum power supply is recommended for Vbias. The Vbias should be able to deliver a minimum of 3v or 2.1V greater than Vout, whichever is greater. In cases where the Vin voltage satisfies the minimum Vbias voltage, one supply can be used.
