General Description

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

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

enable (EN) of the Slave so that it turns on after the

Master and turns off before (or after) the Master. This

behavior is critical for power-up and power-down

control in multi-output power supplies. The MIC68200

is fully protected offering both thermal and current limit

protection and reverse current protection.

The MIC68200 has a junction temperature range of

–40°C to +125°C and is available in fixed as well as

an adjustable option. The MIC68200 is offered in the

tiny 10-pin 3mm x 3mm MLF

POR Final Note on Tracking The MIC68200 does not fully shutdown until the output load is discharged to near zero driven from an external source in a tracking configuration, and the external source does not go to zero on shutdown it may prevent complete shutdown of the MIC68200.
