Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2771SD/NOPB

LM2771SD/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2771SD/NOPB is a low-ripple, 250mA switched capacitor step-down DC/DC converter manufactured by Texas Instruments. It operates with an input voltage range of 2.7V to 5.5V and provides a fixed regulated output of 1.5V. The device features an adjustable current limit and operates within a temperature range of -30°C to 110°C. It utilizes a 10-pin WSON package and supports switching frequencies between 800kHz and 1400kHz.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Low-ripple switched capacitor architecture for clean power delivery
Adjustable current limit protection mechanism
Fixed 1.5V regulated output capability

Voltage Regulators - DC DC Switching Regulators Applications

Portable electronic devices requiring efficient step-down conversion
Battery-powered systems needing stable 1.5V logic supplies
Space-constrained designs utilizing compact WSON packaging

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SD' indicates the tape-and-reel or specific variant configuration as defined in the official datasheet. Confirm the NOPB designation ensures compliance with RoHS standards and absence of lead-based materials. Cross-reference the exact part number against the manufacturer's current product status to ensure availability and manufacturing continuity before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.5V output is required from a 2.7V to 5.5V input source without external feedback resistors. It is suitable for applications prioritizing low ripple and adjustable current limiting over programmable output voltages. Ensure the load current does not exceed the 250mA maximum rating and that the operating environment falls within the specified -30°C to 110°C temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2771 family of low-ripple switched capacitor converters. It serves as an inductorless solution for stepping down voltage in portable electronics. The family includes variants such as LM2771SDX-NOPB and LM2771SDX/NOPB, which share similar electrical characteristics but may differ in packaging quantities or specific reel configurations.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2771SDX-NOPB, LM2771SD-NOPB, and LM2771SDX/NOPB. Verify pin compatibility and package dimensions (10-WSON) when swapping between these variants. Ensure the replacement part maintains the same fixed 1.5V output and 250mA current rating.
