LF50ACP

Overview

The LF50ACP is a very low-dropout linear voltage regulator manufactured by STMicroelectronics, featuring an integrated inhibit function. It provides a fixed 5 V output with a maximum current of 500 mA and a dropout voltage of 0.45 V at 200 mA. The device operates within an input voltage range of 2.5 V to 16 V and maintains an output tolerance of ±1.5%. It supports through-hole mounting in a TO-220-3 package and functions reliably across a temperature range of -40 °C to +125 °C.

Feature Summary

Integrated inhibit function for power management
Very low dropout voltage for efficiency
Fixed 5 V output with high accuracy

Applications

Battery-powered systems
Low-noise applications
Low-power consumer electronics

Procurement Notes

Verify the specific suffix 'ACP' to confirm the presence of the inhibit feature and the tube packaging format. Ensure the procurement source explicitly lists the part as obsolete or available stock, as lifecycle status may affect availability. Cross-reference the manufacturer datasheet to confirm pinout compatibility and thermal requirements for the TO-220-3 package before finalizing orders.

Selection Notes

Select this component when a fixed 5 V rail is required with minimal voltage drop under load. The inhibit pin allows for system-level power control, making it suitable for battery-operated devices where standby current reduction is critical. Verify that the input voltage does not exceed the 16 V maximum rating and that the thermal dissipation capabilities of the TO-220-3 package are sufficient for the expected load conditions.

Part Context

This part belongs to the LFXX series of very low-dropout regulators from STMicroelectronics. The series offers various fixed output voltages optimized for low-noise and low-power applications. The LF50ACP specifically targets designs requiring precise 5 V regulation with the added benefit of an enable/disable control line, distinguishing it from standard LDOs without inhibit functionality.
