LM2771SDX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2771SDX/NOPB is a low-ripple, switched-capacitor step-down DC/DC converter manufactured by Texas Instruments. It operates within an input voltage range of 2.7 V to 5.5 V and provides a fixed output voltage of 1.5 V with a maximum output current of 250 mA. The device utilizes a charge pump topology and functions at a switching frequency between 800 kHz and 1400 kHz. It is housed in a 10-WSON package and supports an operating temperature range from -30°C to 110°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SDX' indicates cut-tape or reel packaging configuration as per manufacturer documentation. Confirm RoHS compliance status through official datasheets. Ensure the component matches the 10-WSON footprint requirements for PCB layout compatibility before integration into production designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, inductorless solution is required for stepping down voltages between 2.7 V and 5.5 V to 1.5 V. It is suitable for applications prioritizing low ripple over high efficiency or high current delivery. Consider the 250 mA output limit and thermal performance within the 10-WSON package for space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2771 series of low-ripple switched-capacitor converters. It serves as a direct replacement for legacy charge pump regulators requiring similar electrical characteristics. The 'NOPB' suffix denotes lead-free and halogen-free construction, aligning with modern environmental standards for electronic components distributed globally.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2771SD/NOPB: Identical electrical specifications but may differ in packaging format (cut tape vs. reel). LM2770SD-1215/NOPB: Similar charge pump topology but offers programmable output voltages instead of fixed 1.5 V.
