Overview
The LE50CZ-AP is a linear voltage regulator IC from STMicroelectronics, providing a fixed positive output of 5V with a maximum current capacity of 100mA. It utilizes a TO-92-3 (TO-226AA) through-hole package with three pins. The device supports a maximum input voltage of 18V and operates at temperatures up to 125°C. Key electrical specifications include a static current of 1.5mA. This component belongs to the LExxAB series and is designed as a very low drop voltage regulator with inhibit functionality.
Feature Summary
- Very low drop voltage regulation capability
- Integrated inhibit control function
- Fixed positive output voltage configuration
Applications
- General purpose linear voltage regulation in electronic circuits
- Battery-powered devices requiring stable 5V supply
- Embedded systems utilizing through-hole mounting
Procurement Notes
Verify the specific suffix 'AP' against the official STMicroelectronics datasheet to confirm it denotes the correct package variant and marking code. Ensure the application circuit accounts for the 1.5mA static current consumption and thermal dissipation limits within the TO-92 package. Confirm that the 18V maximum input rating aligns with your system's supply voltage headroom requirements.
Selection Notes
Select this component when a fixed 5V output is required with moderate current demands up to 100mA. The TO-92 package is suitable for prototyping or applications where through-hole assembly is preferred over surface mount technology. Consider the 1.5mA quiescent current if power efficiency is critical, and ensure the operating temperature range extends to 125°C meets environmental conditions.
Part Context
This part belongs to the LE00 series of very low drop regulators manufactured by STMicroelectronics. The series offers various output voltages and packages, including SO-8 and TO-92. The LE50CZ-AP specifically represents the 5V fixed output version in the TO-92-3 form factor, featuring inhibit functionality for power management control.
Replacement Considerations
Check for other members of the LE00 series with identical pinouts and electrical characteristics. Verify compatibility with any alternative LDO regulators offering 5V output, 100mA current, and TO-92 packaging, ensuring equivalent inhibit functionality and thermal performance.
