The LMZ12010 is available Requirement Applications in an innovative package that enhances thermal performance and allows for hand or machine • Negative Output Voltage Applications soldering. 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.
