MIC5159

Programmable Current Limit µCap LDO Regulator Controller

General Description

Features

Micrel’s MIC5159 is a precision-voltage regulator controller.

Used with an external P-Channel MOSFET, the MIC5159

forms a two-chip low-dropout regulator capable of driving a

wide range of output currents.

• Fast transient response

• Input voltage range: V 1.65V to 5.5V

• ±1.0% initial output tolerance

• Fixed 1.8V or adjustable output voltage down to 1.25V

• Stable with ceramic output capacitor

• Capable up to 10A

• Excellent line and load regulation specifications

• Logic-controlled shutdown

The MIC5159 operates from an input of 1.65V to 5.5V. The

low input voltage allows the MIC5159 to operate off of high

power 1.8V rails to generate lower voltages such as 1.5V.

Features of the MIC5159 include enable input and current-

limit protection. As aµCap design, the MIC5159 is stable with

ceramic output capacitors.

• Programmable current limit

• Current-limit protection

• IttyBitty SOT-23-6 package

The MIC5159 is packaged in the IttyBitty SOT-23-6, and is

• Available temperature range: –40°C to +125°C

offered in fixed and adjustable output voltages. Junction

temperature range of the MIC5159 is from –40°C to +125°C.

Applications

• Ultra-high current, ultra-low dropout voltage regulator

• High-efficiency linear power supplies

• Low-voltage distributed power

• Fixed telecom

• Multimedia and PC power supplies

• Battery chargers

• Low-voltage DSP, microprocessor and microcontroller
