of driving up to 1A load with exceptional power
conversion efficiency, line and load regulation, and
output accuracy. The LMZ14201 is available in an
innovative package that enhances thermal
performance and allows for hand or machine
soldering.
The LMZ14201 can accept an input voltage rail
between 6V and 42V and deliver an adjustable and
highly accurate output voltage as low as 0.8V. The
LMZ14201 only requires three external resistors and
four external capacitors to complete the power
solution. The LMZ14201 is a reliable and robust
design with the following protection features: thermal
shutdown, input under-voltage lockout, output over-
voltage protection, short-circuit protection, output
current limit, and allows startup into a pre-biased
output. A single resistor adjusts the switching
