MIC68401

MIC68401 4A Sequencing LDO with Tracking and Ramp Control™ General Description The MIC68401 is a high peak current LDO regulator designed specifically for powering applications such as FPGA core voltages that require high startup current with lower nominal operating current. Capable of sourcing 4A of current for start-up, the MIC68401 provides high power from a small QFN package. The MIC68401 can also implement a variety of power-up and power-down protocols such as sequencing, tracking, and ratiometric tracking. The MIC68401 operates from a wide input range of 1.65V to 5.5V, which includes all of the main supply voltages commonly available today. It is designed to drive digital circuits requiring low voltage at high currents (i.e., PLDs, DSPs, microcontrollers, etc.). The MIC68401 incorporates a delay pin (DELAY) for control of power-on-reset (POR) output at turn-on. In addition, there is a ramp control (RC) for either tracking applications or output voltage slew rate control at tur...
