Overview
The LE50ABZ-TR is a positive fixed linear voltage regulator from the LExxAB series by STMicroelectronics. It provides a fixed output voltage of 5V with a maximum output current of 100mA. The device operates with an input voltage up to 18V and features a low dropout voltage of 0.5V at full load. Key electrical parameters include a quiescent current of 1mA, power supply rejection ratio (PSRR) ranging from 76dB to 60dB across frequencies, and protection against overcurrent and thermal overload. It is housed in a TO-92-3 package suitable for through-hole mounting.
Feature Summary
- Provides stable 5V regulated output with 100mA load capability
- Includes internal overcurrent and thermal shutdown protection
- Operates within extended temperature range of -40°C to 125°C
Applications
- General purpose linear regulation
- Low noise power supply circuits
- Battery-powered equipment requiring low quiescent current
Procurement Notes
Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the component matches the LExxAB series specifications. Ensure the TO-92-3 package type aligns with board layout requirements. Check for RoHS compliance status if required by project standards.
Selection Notes
Select this component for applications requiring a simple, low-cost 5V regulator. It is suitable where input voltages do not exceed 18V. Consider the 100mA current limit for load requirements. The TO-92 package is appropriate for prototyping or low-volume through-hole designs.
Part Context
This part belongs to the LExx family of linear regulators. It shares functional similarities with other members like LE50ABZ-AP but differs in packaging format. The TR suffix typically denotes reel packaging for automated assembly processes.
