Adjustable Regulator Design
The adjustable regulator version, MIC29712, allows pro-
gramming the output voltage anywhere between 1.25V and
the 16V maximum operating rating of the family. Two resis-
tors are used. Resistors can be quite large, up to 100k
,
because of the very high input impedance and low bias
current of the sense comparator. The resistor values are
calculated by:
V

R1 = R2

( ——— – 1)
1.240
Where V
O
is the desired output voltage. Figure 4 shows
component definition.

Enable Input
The MIC29712 versions features an enable (EN) input that
allows ON/OFF control of the device. Special design allows
“zero” current drain when the device is disabled—only micro-
amperes of leakage current flows. The EN input has TTL/
CMOS compatible thresholds for simple interfacing with
logic, or may be directly tied to V
IN
. Enabling the regulator
requires approximately 20
μ
A of current into the EN pin.
