LF120CDT

Overview

The LF120CDT is a fixed-output linear regulator from the LFXX series, providing a stable 12V output with a maximum current of 0.5A. It operates within an input voltage range of -0.5V to 40V and features a low dropout voltage of 0.7V at full load. The device includes overcurrent and thermal overload protection and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

Very low dropout voltage for efficient power conversion in battery-powered systems
Integrated overcurrent and thermal overload protection for enhanced reliability
Low quiescent current suitable for low-noise and low-power applications

Applications

Battery powered systems requiring low noise and low power consumption
General purpose DC to DC conversion circuits
Low drop voltage regulator supply designs

Procurement Notes

Verify component status as the LF120CDT is listed as obsolete and no longer manufactured. Confirm availability of replacement parts such as the LF120CDT-TR before procurement. Ensure compatibility with existing PCB footprints and verify that the DPAK package meets mechanical requirements for the target application.

Selection Notes

Select this component for applications requiring a fixed 12V output with moderate current capability. Consider the LF120CDT-TR as a direct alternative if tape and reel packaging is preferred. Evaluate thermal management needs given the TO-252-3 package and operating temperature range. Verify input voltage stability to ensure operation within the specified limits.

Part Context

The LF120CDT belongs to the LFXX family of very low drop regulators available in various output voltages. Manufactured by STMicroelectronics, it is designed for efficiency in low-power scenarios. The part utilizes a surface-mount DPAK package, integrating essential protection features typical of modern linear regulators for robust performance in compact designs.
