Overview
The onsemi L78M05T-TL-E is a linear voltage regulator IC designed for general-purpose applications. It provides a fixed positive output voltage of 5 V with a maximum output current capability of 500 mA. The device operates within an input voltage range from 7 V to 35 V, ensuring stable regulation under varying supply conditions. It features internal thermal overload protection and short-circuit current limiting to safeguard against operational faults. The component is housed in a surface-mount reel packaging format, suitable for automated assembly processes.
Feature Summary
- Provides a fixed 5 V positive output voltage
- Supports up to 500 mA load current
- Includes internal thermal overload protection
- Features short-circuit current limiting
Applications
- General-purpose power supply regulation
- Battery-powered equipment voltage stabilization
- Embedded system power management
Procurement Notes
Verify the specific suffix 'TL-E' to confirm the tape-and-reel packaging configuration, as other suffixes may indicate different package types or quantities. Confirm RoHS compliance status through official datasheets or supplier documentation before integration. Ensure the procurement channel is authorized to guarantee component authenticity and traceability.
Selection Notes
Select this component when a fixed 5 V output is required with moderate current demands up to 500 mA. It is suitable for designs prioritizing simplicity and cost-effectiveness over high efficiency. Consider the thermal dissipation requirements based on the input-output voltage differential and ambient operating temperature constraints.
Part Context
This part belongs to the L78Mxx series of three-terminal linear regulators manufactured by onsemi. The series is known for its robustness and ease of use in standard voltage regulation tasks. The 'M' designation typically indicates a 500 mA current rating, distinguishing it from higher or lower current variants within the broader family.
Replacement Considerations
Direct substitutes include MC78M05CTG and L78M05TLL-E. Verify pinout compatibility and electrical specifications such as dropout voltage and thermal resistance before substitution.
