LT1054CS8#TRPBF

Voltage Regulators - DC DC Switching Regulators Overview

The LT1054CS8#TRPBF is a monolithic, bipolar switched-capacitor voltage converter and regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 3.5 V to 15 V and delivers up to 100 mA output current through a single output channel. The device utilizes a charge pump topology with a fixed switching frequency of 25 kHz. It features an adaptive switch driver scheme that optimizes efficiency across wide output current ranges, maintaining a typical total voltage loss of only 1.1 V at 100 mA. The component includes a shutdown function and is housed in an 8-pin SOIC package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when sourcing. Confirm RoHS compliance status via official documentation before integration. Ensure the SOIC-8 footprint matches your PCB design constraints. Check for any recent PCN updates regarding material or manufacturing site changes. Validate supply availability as distribution may be restricted in certain regions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a low-cost, high-current switched-capacitor solution is required without inductors. Consider the 25 kHz switching frequency for EMI sensitivity. Evaluate the 100 mA limit against peak load requirements. Compare voltage drop performance against inductive alternatives for space-constrained designs. Verify input voltage stability within the 3.5 V to 15 V window.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LT1054 series of switched-capacitor regulators. It shares functional similarities with the LT1054IS8#TRPBF but differs in temperature grade and packaging format.
