See AN-2027 SNVA425.

The LMZ12010 can accept an input voltage rail

between 6V and 20V and deliver an adjustable and

highly accurate output voltage as low as 0.8V. The

LMZ12010 only requires two external resistors and

external capacitors to complete the power solution.

The LMZ12010 is a reliable and robust design with

the following protection features: thermal shutdown,

programmable input under-voltage lockout, output

over-voltage protection, short-circuit protection, output

current limit, and allows startup into a pre-biased

output.
