The LMZ12002 SIMPLE SWITCHER^® power module is an easy-to-use step-down DC-DC solution capable of driving up to 2-A load with exceptional power conversion efficiency, line and load regulation, and output accuracy. The LMZ12002 is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.

The LMZ12002 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 LMZ12002 only requires three external resistors and four external capacitors to complete the power solution. The LMZ12002 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.
