The innovative package contains the • Adjustable Output Voltage Range of 0.8 V to 3.6 V regulator and inductor in a small 3.5 mm x 3.5 mm x • ± 1% Feedback Tolerance Over Temperature 1.75 mm volume, thus saving board space and eliminating the time and expense of inductor • 2.4 µA (max) Quiescent Current In Shutdown selection. The LMZ20502 requires only five external • 3 MHz Fixed PWM Switching Frequency components and has a pin-out designed for simple, • -40°C to 125°C Junction Temperature Range optimum PCB layout. The LMZ20502 is a member of • Power Good Flag Function Texas Instruments' SIMPLE SWITCHER family. The SIMPLE SWITCHER concept provides for an easy to • Pin-Selectable Switching Modes use complete design with a minimum number of • Internal Compensation and Soft-Start external components and the TI WEBENCH® design • Current Limit, Thermal Shutdown, and UVLO tool. TI's WEBENCH tool includes features such as Protection external component calculation, electrical simulation, and WebTherm™.
