LE50CZ

Overview

The LE50CZ is a very low drop voltage regulator (LDO) manufactured by STMicroelectronics, designed for applications requiring stable fixed output voltages. It features a maximum input voltage of 18V and offers an output current capability of up to 100mA. The device operates with a typical dropout voltage of 500mV at full load and maintains line regulation within 30mV. It is housed in a TO-92-3 through-hole package, suitable for space-constrained designs. The component supports a maximum operating temperature of 125°C and includes inhibit functionality for power management optimization.

Feature Summary

Provides fixed positive voltage regulation with low dropout characteristics
Integrates inhibit control for enhanced power management capabilities
Designed for high efficiency in portable and battery-powered electronics

Applications

Portable electronic devices such as smartphones and tablets
Battery-powered consumer electronics requiring stable voltage rails
General-purpose linear regulation in compact embedded systems

Procurement Notes

Verify the specific suffix or variant when ordering, as availability may vary. Confirm that the TO-92-3 package matches your PCB footprint requirements. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing design-in decisions. Ensure thermal dissipation considerations are addressed for the chosen application environment.

Selection Notes

Select this component when a fixed 5V output is required with minimal voltage drop across the regulator. Consider the 100mA current limit and 18V maximum input rating against your system's power budget. Evaluate the TO-92 package constraints regarding thermal performance and board space compared to surface-mount alternatives.

Part Context

The LE50CZ belongs to the LExxAB series of low-dropout regulators from STMicroelectronics. This family focuses on providing reliable voltage regulation with low quiescent current consumption. The device is part of a broader portfolio of linear regulators aimed at optimizing power efficiency in mobile and handheld applications.
