Voltage Regulators - DC DC Switching Regulators datasheet and documents for LT1054CPE4

LT1054CPE4

Voltage Regulators - DC DC Switching Regulators Overview

The LT1054CPE4 is a switched-capacitor voltage converter manufactured by Texas Instruments, housed in an 8-pin PDIP package. It operates with an input voltage range of 3.5 V to 15 V and provides a fixed -5 V output at up to 100 mA. The device features a switching frequency of 25 kHz and a typical quiescent current of 100 uA. Designed for through-hole mounting, it functions within a temperature range of 0°C to +70°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated switched-capacitor topology supporting both boost and buck configurations
Fixed negative voltage generation capability without external inductors
Low static current consumption for efficient power management

Voltage Regulators - DC DC Switching Regulators Applications

RS-232 communication interface biasing
Single-supply operational amplifier dual-rail conversion
Portable instrumentation requiring negative rail generation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status against the manufacturer's latest documentation. Confirm the PDIP-8 package availability and ensure the operating temperature range meets the application requirements. Cross-reference the datasheet revision to validate electrical characteristics before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, inductor-less solution is required for generating a negative supply rail from a single positive source. Ensure the load current does not exceed 100 mA and that the input voltage remains within the 3.5 V to 15 V window. Consider the 25 kHz switching frequency for electromagnetic interference compatibility in sensitive analog circuits.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LT1054 series of switched-capacitor regulators. It serves as a legacy alternative to modern synchronous converters, offering simplicity in design for low-power applications. The PDIP-8 package facilitates easy prototyping and through-hole assembly in industrial or educational environments where surface-mount technology is less preferred.
