LM2770SD-1215/NOPB TI DC-DC Converter | 10-WSON (3X3) | 1.2V/1.5V Output, 250mA

Product Overview

The LM2770SD-1215/NOPB is a high-performance switched capacitor voltage converter from Texas Instruments, designed to generate regulated output voltages of 1.2V and 1.5V from a single lithium-ion battery input. Housed in a compact 10-WSON (3x3 mm) package, this device delivers up to 250 mA of output current with high efficiency, making it ideal for space-constrained portable applications. The LM2770SD-1215/NOPB features low ripple, low noise, and requires only a few external components, simplifying design and reducing board space.
