Overview
The L79M05T-TL-E is a negative fixed voltage linear regulator manufactured by onsemi. It provides a stable -5 V output with a maximum continuous output current of 500 mA. The device features a typical power supply rejection ratio (PSRR) of 65 dB and a dropout voltage of 1.1 V. Line regulation is specified at 7 mV, while load regulation is 10 mV. The output voltage range spans from -5.2 V to -4.8 V. It operates within a temperature range of -30 °C to +80 °C and utilizes a TP-3H package.
Feature Summary
- Delivers a fixed negative voltage output for stable power supply applications
- Supports up to 500 mA continuous load current capability
- Provides high ripple rejection performance through internal circuitry
Applications
- Negative rail generation in dual-supply electronic systems
- Power management modules requiring stable negative bias voltages
- General-purpose linear regulation in industrial control circuits
Procurement Notes
Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm package integrity and pin alignment against the TP-3H specification sheet. Ensure storage conditions comply with moisture sensitivity levels prior to assembly. Cross-reference datasheet revisions to confirm parameter consistency with design requirements.
Selection Notes
Select this component when a fixed negative voltage rail is required with moderate current demands. Compare line and load regulation specifications against system tolerance limits. Evaluate thermal dissipation requirements based on input-output voltage differentials and ambient operating temperatures. Verify compatibility with existing PCB footprint constraints for the TP-3H package.
Part Context
This part belongs to the L79M series of negative linear regulators produced by onsemi. It serves as a dedicated solution for generating negative supply rails in mixed-signal and analog circuits. The device integrates internal current limiting and thermal shutdown protection mechanisms to ensure operational safety under fault conditions.
Replacement Considerations
