DESCRIPTION (CONTINUED)
The LMZ10505EXT can accept an input voltage rail between 2.95V and 5.5V and deliver an adjustable and
highly accurate output voltage as low as 0.8V. One megahertz fixed frequency PWM switching provides a
predictable EMI characteristic. Two external compensation components can be adjusted to set the fastest
response time, while allowing the option to use ceramic and/or electrolytic output capacitors. Externally
programmable soft-start capacitor facilitates controlled startup. The LMZ10505EXT is a reliable and robust
solution with the following features: lossless cycle-by-cycle peak current limit to protect for over current or short-
circuit fault, thermal shutdown, input under-voltage lock-out, and pre-biased startup.
