LT1054LCS8#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LT1054LCS8#PBF is a monolithic, bipolar switched-capacitor voltage converter and regulator manufactured by Analog Devices. It operates within an input voltage range of 3.5 V to 7 V and delivers an output current of 125 mA through a single adjustable output channel. The device utilizes a charge pump topology with a switching frequency of 25 kHz and features a shutdown function. Packaged in an 8-pin SOIC, it supports surface-mount installation and functions across an operating temperature range of 0°C to +100°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and thermal grade. Confirm RoHS compliance status via the manufacturer datasheet. Check authorized distributor availability as supply may be restricted or limited. Ensure the selected variant matches the required input voltage constraints and output current specifications for the target design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an input voltage range of 3.5 V to 7 V is required with up to 125 mA output capability. The SOIC-8 package suits surface-mount designs needing compact footprints. Consider the 25 kHz switching frequency for EMI sensitivity. Verify that the adjustable output configuration meets the circuit's voltage regulation needs without external feedback complexity beyond standard resistor networks.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LT1054 series of switched-capacitor converters. Unlike the LT1054CS8 which supports up to 15 V input and 100 mA output, the LT1054LCS8 variant is optimized for lower input voltages (up to 7 V) while providing higher output current (125 mA). Both share the same core architecture and SOIC-8 packaging but differ in electrical ratings.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LT1054CS8#PBF offers similar functionality but with a 15 V maximum input and 100 mA output current. LT1054IS8 variants provide industrial temperature ranges. Verify input voltage compatibility and output current requirements before substituting.
