MIC5233

High Input Voltage, Low I_QµCap LDO Regulator

Features

General Description

• AEC-Q100 Qualified and PPAP Capable;

Available for 5-Lead SOT23 Package Only

The MIC5233 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 MIC5233 ideal for multicell

Li-Ion battery systems.

• Wide Input Voltage Range: 2.3V to 36V

• Ultra-Low Ground Current: 18 µA

• Low Dropout Voltage of 270 mV at 100 mA

• High Output Accuracy of ±2.0% Overtemperature

A µCap LDO design, the MIC5233 is stable with either

ceramic or tantalum output capacitors. It only requires

a 2.2 µF output capacitor for stability.

• µCap: Stable with Ceramic or Tantalum

Capacitors

Features of the MIC5233 include enable input, thermal

shutdown, current limit and reverse battery protection,

and reverse leakage protection.

• Excellent Line and Load Regulation Specifications

• Near Zero Shutdown Current: Typical 0.1 µA

• Reverse Battery Protection

Available in fixed and adjustable output voltage ver-

sions, the MIC5233 is offered in the 5-lead SOT23 and

3-lead SOT223 packages with a junction temperature

range of –40°C to +125°C.

• Reverse Leakage Protection

• Thermal Shutdown and Current Limit Protection

• 5-Lead SOT23 and 3-Lead SOT223 Packages

Applications

• Keep-Alive Supply in Notebook and Portable

Computers

Typical Application Circuit

Ultra-Low Current Adjustable Regulator

Application

• USB Power Supply

• Logic Supply for High-Voltage Batteries
