Ultra-Low Quiescent Current, 150mA
μ
Cap LDO Regulator
General Description
The MIC5235 is a 150mA highly accurate, low dropout
regulator with high input voltage and ultra-low ground current.
This combination of high voltage and low ground current
makes the MIC5235 ideal for USB and portable electronics
applications, using 1-cell, 2-cell or 3-cell Li-Ion battery inputs.
A
μ
Cap LDO design, the MIC5235 is stable with either
ceramic or tantalum output capacitor. It only requires a 2.2
μ
F
capacitor for stability.
Features of the MIC5235 includes enable input, thermal
shutdown, current limit, reverse battery protection, and
reverse leakage protection.
Available in fixed and adjustable output voltage versions, the
MIC5235 is offered in the IttyBitty SOT-23-5 package with
a junction temperature range of –40
°
C to +125
