LTC1682IS8#TRPBF

Voltage Regulators - DC DC Switching Regulators Overview

The LTC1682IS8#TRPBF is a Doubler Charge Pump with Low Noise Linear Regulator manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 1.8V to 4.4V and provides a fixed output of 3.3V at up to 50mA. The device features a typical quiescent current of 1µA and a switching frequency of 550kHz. It includes an internal shutdown function for power management. Packaged in an 8-MSOP (0.118 inch, 3.00mm wide) surface-mount case, it supports an operating temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a doubler charge pump topology with a low noise linear regulator for stable output generation.
• Features ultra-low static current consumption suitable for battery-powered applications.
• Includes an internal shutdown pin to minimize power usage during inactive periods.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable handheld devices requiring efficient voltage boosting
• Battery-operated systems needing low quiescent current regulation
• Applications requiring a compact solution for generating higher voltages from low input sources

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing components. Confirm that the part number corresponds to the fixed 3.3V output variant rather than adjustable or other voltage options within the LTC1682 family. Ensure compatibility with 8-MSOP footprints during PCB layout verification.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a small form factor is required alongside high efficiency from a low input voltage source. The integrated linear regulator helps reduce output noise compared to standard charge pumps alone. Consider the 50mA output limit and 550kHz switching frequency constraints for filter design and load requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LTC1682 series of DC/DC converters designed for space-constrained portable electronics. It combines charge pump voltage doubling capabilities with linear regulation to provide clean power. The IS8 designation specifies the SOIC/MSOP package style, while the #TRPBF suffix denotes lead-free tape and reel manufacturing compliant with RoHS standards.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include MAX932ESA+ and MAX932ESA+T from Maxim Integrated. These alternatives offer similar functionality but require verification of pinout compatibility and electrical parameter alignment before integration into existing designs.
