LF85CP

Overview

The LF85CP is a fixed-output linear voltage regulator from the STMicroelectronics LF series, designed for surface-mount installation in DPAK packages. It provides a stable 8.5 V output with a maximum load current of 500 mA. The device operates within an input voltage range of 9.5 V to 16 V and supports an ambient temperature range from -40 °C to +125 °C. Key electrical characteristics include a quiescent current of 12 mA, line regulation of 42 mV, and load regulation of 42 mV. This component is AEC-Q100 qualified for automotive applications.

Feature Summary

Provides a fixed positive output voltage regulated at 8.5 V
Capable of delivering up to 500 mA continuous load current
Includes inhibit functionality with low standby current consumption
Qualified for automotive environments under AEC-Q100 standards

Applications

Automotive electronic systems requiring robust power management
Industrial equipment operating in high-temperature environments
Consumer electronics utilizing surface-mount assembly processes

Procurement Notes

Verify the specific suffix (e.g., CD vs CP) against official datasheets to confirm package type and thermal performance. Confirm availability status as distribution channels may list obsolete or end-of-life inventory. Ensure compliance with RoHS and REACH directives relevant to your region before finalizing procurement orders.

Selection Notes

Select this regulator when a fixed 8.5 V supply is required with moderate current demands. Consider the DPAK package for its thermal dissipation capabilities in compact designs. Verify that the input voltage remains within the specified 9.5 V to 16 V window to ensure proper regulation and prevent dropout conditions during operation.

Part Context

This component belongs to the LF series of low-dropout regulators manufactured by STMicroelectronics. These devices are engineered for general-purpose power management tasks. The LF85CP variant specifically targets applications needing reliable voltage stabilization in automotive and industrial sectors where wide temperature tolerance is essential.
