Adjustable Regulator Design
The MIC49300 adjustable version allows programming the
output voltage anywhere between 0.9Vand 5V. Two resistors
are used. The resistor value between V
should not exceed 1kΩ. Larger values can cause instability.
The resistor values are calculated by:
Where V
Enable
The fi xed output voltage versions of the MIC49300 feature an
active high enable input (EN) that allows on-off control of the
regulator. Current drain reduces to “zero” when the device is
sn}tñ◊wn, with only microamperes of leakage current. The
EN input has TTL/CMOS compatible thresholds for simple
logic interfacing. EN may be directly tied to V
up to the maximum supply voltage
