MIC5270
IttyBitty Negative Low-Dropout Regulator
Preliminary Information
General Description
The MIC5270 is a
μ
Cap 100mA negative regulator in a SOT-
23-5 package. With better than 2% initial accuracy, this
regulator provides a very accurate supply voltage for applica-
tions that require a negative rail. The MIC5270 sinks 100mA
of output current at very low dropout voltage (600mV maxi-
mum at 100mA of output current).
The
μ
Cap regulator design is optimized to work with low-
value, low-cost ceramic capacitors. The output typically re-
quires only a 1
μ
F capacitance for stability.
Designed for applications where small packaging and effi-
ciency are critical, the MIC5270 combines LDO design exper-
tise with IttyBitty
packaging to improve performance and
reduce power dissipation. Ground current is optimized to help
improve battery life in portable applications.
The MIC5270 is available in the SOT-23-5 package for space
saving applications and it is available with fixed –3.0V, –4.1V,
and –5.0V outputs.
