Overview
The L78L05ABD is a three-terminal positive linear voltage regulator from the L78L series, manufactured by STMicroelectronics. It provides a fixed output voltage of 5V with a maximum output current capability of 100 mA. The device features an absolute maximum DC input voltage rating of 30V and operates within a junction temperature range of -40°C to 125°C. It utilizes internal current limiting and thermal shutdown mechanisms for protection. The component is housed in an 8-pin SOIC surface-mount package.
Feature Summary
- Integrates internal current limiting and thermal shutdown protection mechanisms
- Designed as a fixed voltage regulator requiring no external components
- Capable of local or on-card regulation to eliminate noise associated with single-point regulation
Applications
- Local or on-card voltage regulation
- Replacement for Zener diode and resistor combinations
- Construction of high-current voltage regulators when used with power pass elements
Procurement Notes
Verify that the specific part number matches the required tolerance grade (A selection) and package type (SOIC-8). Confirm the operating temperature range requirements align with the AB suffix specifications. Ensure compatibility with standard surface mount assembly processes for the SOIC package.
Selection Notes
Select this component for applications requiring a fixed 5V output with up to 100 mA load current. The wide input voltage range supports various supply configurations. Consider the thermal resistance characteristics of the SOIC package and ensure adequate copper area on the PCB for heat dissipation to maintain performance within the specified temperature limits.
Part Context
This component belongs to the L78L series of three-terminal positive regulators. The 'AB' designation indicates a specific output voltage tolerance grade and extended operating temperature range compared to other variants in the family. The 'D' suffix denotes the SOIC surface-mount package configuration.
