The LMZ12002 SIMPLE SWITCHER® power module APPLICATIONS is an easy-to-use step-down DC-DC solution capable
• Point of Load Conversions from 5V and 12V of driving up to 2A load with exceptional power
Input Rail conversion efficiency， line and load regulation， and
output accuracy. The LMZ12002 is available in an
• Time Critical Projects innovative package that enhances thermal
• Space Constrained High Thermal Requirement performance and allows for hand or machine
Applications soldering.
• Negative Output Voltage Applications The LMZ12002 can accept an input voltage rail
（See AN-2027） between 4.5V and 20V and 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 under-voltage lockout， output overvoltage protection， short-circuit protection， output
current limit， and allows startup into a pre-biased
output. A single resistor adjusts the switching
frequency up to 1 MHz
