Error Flag

MIC29xx1 and MIC29xx3 versions feature an Error Flag,

which looks at the output voltage and signals an error

condition when this voltage drops 5% below its expected

value. The error flag is an open-collector output that

pulls low under fault conditions. It may sink 10mA. Low

output voltage signifies a number of possible problems,

including an overcurrent fault (the device is in current

limit) and low input voltage. The flag output is inoperative

during overtemperature shutdown conditions.

Enable Input

MIC29xx1 and MIC29xx2 versions feature an enable

(EN) input that allows ON/OFF control of the device.

Special design allows “zero” current drain when the

device is disabled—only microamperes of leakage

current flows. The EN input has TTL/CMOS compatible

thresholds for simple interfacing with logic, or may be

directly tied to ≤30V. Enabling the regulator requires

approximately 20µA of current.
