MIC5271
μ Cap Negative Low-Dropout Regulator
Features
The MIC5271 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 MIC5271 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-

reduce power dissipation. Ground current is optimized to help
improve battery life in portable applications. The MIC5271
also includes a TTL-compatible enable pin, allowing the user
to put the part into a zero-current off-mode.
The MIC5271 is available in the SOT-23-5 package for space
