Micrel MIC68400 LDO Regulators
Micrel’s (Nasdaq: MCRL) 4A MIC68400 is the latest addition to their MIC68000 family of LDOs designed specifically for powering FPGA, CPLDs, DSPs and microcontrollers. The devices are aimed at applications such as broadband modems, routers, servers, storage networks, and wireless base stations. The MIC68400 is currently available in volume with pricing starting at 2.50 for 1K quantities.
The MIC68400 supports various power-up and power-down protocols such as sequencing, tracking, and ratiometric tracking that can be implemented very easily with the use of few passive components. Additionally, multiple MIC68400 and/or other devices within the MIC68000 family can be daisy-chained together for a complete synchronized system power-up and power-down. The IC operates from a wide input range of 1.65V to 5.5V and supports an output voltage as low as 0.5V with 2 percent accuracy. Integrated protection features include thermal, current limit and reverse current protection. The MIC68400 is offered in a tiny 16-lead 4mm x 4mm MLF(R) package.
