3 Description

The LMZ12003 SIMPLE SWITCHER® power module is an easy-to-use step-down DC-DC solution capable

of driving up to 3-A load with exceptional power

conversion efficiency, line and load regulation, and

output accuracy. The LMZ12003 is available in an

innovative package that enhances thermal

performance and allows for hand or machine

soldering.

The LMZ12003 can accept an input voltage rail

between 4.5 V and 20 V and can deliver an

adjustable and highly accurate output voltage as low

as 0.8 V. The LMZ12003 only requires three external

resistors and four external capacitors to complete the

power solution. The LMZ12003 is a reliable and

robust design with the following protection features:

thermal shutdown, input undervoltage lockout, output overvoltage protection, short circuit protection, output

current limit, and this device allows start-up into a

prebiased output. A single resistor adjusts the

switching frequency up to 1 MHz.
