The LMZ12003EXT 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 LMZ12003EXT is available in an innovative package that enhances thermal performance
and allows for hand or machine soldering.
The LMZ12003EXT 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 LMZ12003EXT only requires
three external resistors and four external capacitors to complete the power solution. The
LMZ12003EXT 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 the device allows start-up into a prebiased output. A single resistor
adjusts the switching frequency up to 1 MHz.
