MIC68200
2A Sequencing LDO with Tracking
and Ramp Control?
General Description
Features
The MIC68200 is a 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 for start-up, the MIC68200
provides high power from a small MLF ? leadless
package. The MIC68200 can also implement a variety
of power-up and power-down protocols such as
sequencing, tracking, and ratiometric tracking.
The MIC68200 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, DSP, microcontroller, etc.). The
MIC68200 incorporates a delay pin (DLY) for control
of power on reset output (POR) at turn-on and power-
down delay at turn-off. In addition there is a ramp
control pin (RC) for either tracking applications or
output voltage slew rate adjustment at turn-on. This is
important in applications where the load is highly
capacitive and in-rush currents can cause supply
voltages to fail and microprocessors or other complex
logic chips to hang up.
Multiple MIC68200s can be daisy chained in two
modes. In tracking mode the output voltage of the
Master drives the RC pin of a Slave so that the Slave
tracks the main regulator during turn-on and turn-off.
In sequencing mode the POR of the Master drives the
