L79M05TL-E

Overview

The L79M05TL-E is a fixed negative linear voltage regulator manufactured by onsemi, designed for applications requiring stable -5 V output. It delivers a maximum output current of 500 mA with a typical dropout voltage of 1.1 V. The device operates within an input voltage range of -20 V to -7.5 V and provides a typical power supply rejection ratio (PSRR) of 65 dB. Line regulation is specified at 7 mV, while load regulation is 10 mV. The output voltage tolerance ranges from -4.8 V to -5.2 V. It functions reliably across an operating temperature range of -30°C to +80°C.

Feature Summary

Provides a fixed negative output voltage suitable for standard logic and analog circuits.
Includes internal thermal overload and short-circuit protection mechanisms.
Utilizes a through-hole package configuration for reliable mounting.

Applications

Negative power supply rails in electronic instrumentation
General-purpose linear regulation in industrial control systems
Power conditioning for mixed-signal circuit boards

Procurement Notes

Verify component authenticity through authorized distribution channels due to the part's end-of-life status. Confirm RoHS compliance details as indicated in official documentation before integration. Ensure that the specific manufacturing lot aligns with project requirements for legacy system maintenance or replacement strategies.

Selection Notes

Select this component when a fixed -5 V negative rail is required with moderate current capabilities up to 500 mA. Consider its through-hole packaging if board space allows for larger footprints. Evaluate the -30°C to +80°C operating range against environmental conditions to ensure adequate thermal margins for long-term reliability.

Part Context

This regulator belongs to the L79M series of negative voltage regulators, which are widely recognized for their robustness in power management applications. The 'M' suffix typically denotes a 500 mA current rating variant, distinguishing it from higher-current counterparts like the L79xx series. It serves as a fundamental building block for creating dual-polarity power supplies alongside positive regulators.
