LT1054IS8#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LT1054IS8#PBF 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 an output current of 100 mA. The device utilizes a charge pump topology with a switching frequency of 25 kHz. It provides adjustable or fixed outputs (2.5V, -Vin, 2Vin) in an 8-pin SOIC package. Key electrical parameters include a typical total voltage loss of 1.1 V at 100 mA output and a static current of 2.5 mA. The component supports shutdown functionality and operates across a temperature range of -40°C to +100°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when ordering. Confirm the IS8 variant corresponds to the industrial temperature grade (-40°C to +100°C). Ensure the 8-pin SOIC footprint matches the target PCB design. Cross-reference the manufacturer part number LT1054IS8#PBF with authorized distributors to confirm current availability status.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring high output current from switched-capacitor topologies. The adaptive drive scheme makes it suitable for varying load conditions where efficiency is critical. Consider the 25 kHz switching frequency for EMI constraints. The 8-pin SOIC package offers surface-mount convenience. Verify that the 3.5 V minimum input voltage aligns with the system power source.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LT1054 series of switched-capacitor converters. It shares functional similarities with other variants like LT1054LCS8 but differs in temperature rating and package type. The IS8 designation specifically denotes the industrial grade performance in an SOIC-8 housing. It serves as a compact solution for generating negative or doubled voltages without inductors.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LT1054IS8#TRPBF: Same electrical specifications and pinout; differs only in tape-and-reel packaging instead of tube. LT1054IN8#PBF: Identical function but housed in an 8-pin PDIP package rather than SOIC. LT1054LCS8#PBF: Similar charge pump function but specified for commercial temperature range (0°C to 70°C) instead of industrial.
