MIC5236

Low Quiescent Current µCap LDO Regulator

Preliminary Information

General Description

Features

The MIC5236 is a low quiescent current, µCap low-dropout

regulator. With a maximum operating input voltage of 30V

andaquiescentcurrentof20µA, itisidealforsupplyingkeep-

alive power in systems with high-voltage batteries.

• Ultra-low quiescent current (I = 20µA @I = 100µA)

• Wide input range: 2.3V to 30V

• Low dropout:

230mV @50mA;

300mV @150mA

• Fixed 2.5V, 3.0V, 3.3V, 5.0V, and Adjustable outputs

• ±1.0% initial output accuracy

• Stable with ceramic or tantalum output capacitor

• Load dump protection: –20V to +60V input transient

survivability

• Logic compatible enable input

• Low output flag indicator

• Overcurrent protection

• Thermal shutdown

• Reverse-leakage protection

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 µCap LDO, the MIC5236 is stable with either a ceramic

or a tantalum output capacitor. It only requires a 1.0µF output

capacitor for stability.

TheMIC5236includesalogiccompatibleenableinputandan

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.

• Reverse-battery protection

AvailableinthethermallyenhancedSOP-8andMSOP-8, the

MIC5236 comes in fixed 2.5V, 3.0V, 3.3V, 5.0V, and adjust-

able voltages. For other output voltages, contact Micrel.

• High-power SOP-8 and MSOP-8

Applications

• Keep-alive supply in notebook and

portable personal computers

• Logic supply from high-voltage batteries

• Automotive electronics

• Battery-powered systems
