Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'VT' indicates a tape-and-reel packaging configuration distinct from the 'DBVR' cut-tape variant. Confirm the manufacturer part number matches the specific package outline and marking code provided in the official datasheet. Ensure compatibility with the required operating temperature range and electrical specifications before integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed to generate a negative voltage rail from a single positive source. It is suitable for applications where space constraints prohibit the use of inductive converters. Consider the 200 mA current limit and input voltage range to ensure adequate performance for the target load requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2776 family of switched-capacitor inverters manufactured by Texas Instruments. It shares core functionality with other variants in the series but differs in packaging and reel configuration. The family addresses the need for efficient, small-footprint negative voltage generation in portable electronics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2776DBVR is a compatible alternative offering identical electrical characteristics but packaged in a cut-tape format instead of tape-and-reel.
