MIC5236
Low Quiescent Current
μ
Cap LDO Regulator
Preliminary Information
General Description
The MIC5236 is a low quiescent current,
μ
Cap low-dropout
regulator. With a maximum operating input voltage of 30V
and a quiescent current of 20
μ
A, it is ideal for supplying keep-
alive power in systems with high-voltage batteries.
Capable of 150mA output, the MIC5236 has a dropout
voltage of only 300mV. It can also survive an input transient
of –20V to +60V.
As a
μ
Cap LDO, the MIC5236 is stable with either a ceramic
or a tantalum output capacitor. It only requires a 1.0
μ
F output
capacitor for stability.
The MIC5236 includes a logic compatible enable input and an
undervoltage error flag indicator. Other features of the
MIC5236 include thermal shutdown, current-limit, overvolt-
age shutdown, load-dump protection, reverse leakage pro-
tections, and reverse battery protection.
Available in the thermally enhanced SOP-8 and MSOP-8, the
MIC5236 comes in fixed 2.5V, 3.0V, 3.3V, 5.0V, and adjust-
able voltages. For other output voltages, contact Micrel.
