MIC3490

High Input Voltage, Low I_QµCap LDO Regulator

Features

General Description

• Wide Input Voltage Range: 2.3V to 36V

• Ultra-Low Ground Current: 18 µA

The MIC3490 is a 100 mA, 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 MIC3490

ideal for multi-cell Li-Ion battery systems.

• Low Dropout Voltage of 270 mV at 100 mA

• High Output Accuracy of ±2.0% Overtemperature

• µCap: Stable with Ceramic or Tantalum

Capacitors

As a µCap LDO design, the MIC3490 is stable with

either ceramic or tantalum output capacitors. It only

requires a 2.2 µF output capacitor for stability.

• Excellent Line and Load Regulation Specifications

• Near Zero Shutdown Current: Typical 0.1 µA

• Reverse Battery Protection

Features of the MIC3490 include enable input, thermal

shutdown, current limit, reverse battery protection and

reverse leakage protection.

• Reverse Leakage Protection

• Thermal Shutdown and Current-Limit Protection

• SOT23-5 Package

Available in five output voltage options (1.8V, 2.5V,

3.0V, 3.3V and 5.0V), the MIC3490 is offered in a 5-pin

SOT23 package with a junction temperature range of

-40°C to + 125°C.

• The MIC3490 is Pin-to-Pin Compatible with

LM3940

Applications

• Keep-Alive Supply in Notebook and Portable

Computers
