LT1054CS8#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LT1054CS8#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 through a single adjustable output. The device utilizes a charge pump topology with a switching frequency of 25 kHz. Key electrical parameters include a typical total voltage loss of 1.1 V at 100 mA output, a load regulation of 50 mV, and a static current of 2.5 mA. It functions reliably across an operating temperature range from 0°C to +100°C and is housed in an 8-pin SOIC package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Adaptive switch driver scheme optimizes efficiency across wide output current ranges
• Significantly lower voltage losses compared to previous converter generations
• Integrated shutdown capability for power management control

Voltage Regulators - DC DC Switching Regulators Applications

• Regulating negative voltage conversion (e.g., 12V to -5V)
• Positive voltage regulation from low input sources (e.g., 3.5V to 5V)
• Basic voltage inversion circuits
• Negative voltage multiplier applications

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #PBF indicates lead-free tape-and-reel or tube packaging as per manufacturer documentation. Confirm RoHS compliance status directly with Analog Devices. Check current supply restrictions, as availability may be limited in certain regions. Ensure the SOIC-8 package footprint matches your PCB design requirements before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a high-output current switched-capacitor solution is required with minimal voltage drop over a broad input range. The LT1054CS8#PBF is suitable for designs needing adjustable output regulation without magnetic components. Consider the 25 kHz switching frequency for EMI constraints. Compare against the LT1054L variant if higher current (125 mA) is needed but with a restricted maximum input voltage of 7 V.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LT1054 series of switched-capacitor regulators. It shares the same functional core as the LT1054CN8#PBF (through-hole) and LT1054CS8#TRPBF (reel), differing primarily in package type and shipping quantity. The CS8 designation specifically identifies the surface-mount SOIC-8 form factor used in compact electronic assemblies.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LT1054CN8#PBF offers identical electrical performance in a PDIP-8 through-hole package. LT1054CS8#TRPBF provides the same SOIC-8 functionality in reel packaging. For higher current needs within a 7V limit, consider LT1054LCS8#PBF.
