Microchip | MIC68220YML-TR

The MIC68220 is a dual high peak current LDO regulator designed specifically for powering applications such as FPGA core voltages that require high start up current with lower nominal operating current. Capable of sourcing 2A of current per channel for start-up, the MIC68220 provides high power from a small MLF™ leadless package. The MIC68220 can also implement a variety of power-up and power-down protocols such as sequencing, tracking, and ratiometric tracking.
