Overview
The L78LR05D-LR-E is a linear voltage regulator manufactured by onsemi, belonging to the L78LR series. It provides a fixed positive output voltage of 5 V with a maximum output current capability of 150 mA. The device is designed for through-hole mounting in bulk packaging. It operates within a junction temperature range from -30 °C to +80 °C. This component serves as a standard three-terminal positive voltage regulator suitable for applications requiring stable low-current power supply regulation.
Feature Summary
- Provides a fixed positive regulated output voltage
- Supports through-hole installation for board integration
- Includes internal protection mechanisms against overload conditions
Applications
- General purpose electronic circuit power supply regulation
- Battery-powered equipment requiring stable 5V logic levels
- Embedded systems utilizing low-current microcontrollers
Procurement Notes
Verify the specific suffix LR-E against official onsemi documentation to confirm exact manufacturing lot or tape-and-reel specifications if applicable, although bulk packaging is indicated. Confirm end-of-life status and availability through authorized distributors, as this part may be discontinued. Ensure the supplier provides valid traceability documents matching the manufacturer's part number.
Selection Notes
Select this component when a fixed 5V output at up to 150 mA is required in a through-hole package. Compare input voltage requirements against the dropout voltage characteristics found in the datasheet. Consider thermal dissipation capabilities based on the expected load current and ambient operating temperature limits defined for the -30 °C to +80 °C range.
Part Context
This regulator belongs to the L78LR family of three-terminal positive voltage regulators produced by onsemi. These devices are standard industry replacements for older 78L05 equivalents but offer specific performance characteristics defined by the manufacturer. The series is designed for general-purpose regulation tasks where moderate current and fixed voltage stability are primary requirements.
Replacement Considerations
Cross-reference with MC78L05ABDR2G or similar onsemi parts for surface-mount alternatives. Verify pinout compatibility with other 78Lxx series regulators from different manufacturers before substitution.
