The LMZ12002TZ-ADJ/NOPB is a SIMPLE SWITCHER® Power Module with 20V maximum input voltage. The power module is an easy-to-use step-down DC-DC solution capable of driving up to 2A load with exceptional power conversion efficiency, line and load regulation and output accuracy. It enhances thermal performance and allows for hand or machine soldering. It can accept an input voltage rail between 4.5 and 20V and can deliver an adjustable and highly accurate output voltage as low as 0.8V. 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 pre-biased output. A single resistor adjusts the switching frequency up to 1MHz.
