L78LR05DL-TL-E

Overview

The L78LR05DL-TL-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 supports an operating temperature range from -30 °C to +80 °C and utilizes a through-hole installation style. This component functions as a three-terminal positive regulator designed for stable power supply applications within its specified electrical and thermal limits.

Feature Summary

• Incorporates internal circuitry for current limiting and thermal shutdown protection to ensure operational robustness under fault conditions.

Applications

• Local or on-card regulation to eliminate noise associated with single-point regulation systems.

Procurement Notes

Verify the exact part number suffix against official manufacturer documentation, as variations such as 'TL' may indicate specific tape-and-reel packaging or regional manufacturing variants that do not alter the core electrical function. Confirm availability status directly with authorized distributors, as this component may be subject to discontinuation or limited stock constraints. Ensure compliance with RoHS and REACH directives relevant to your region before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5 V output at up to 150 mA is required in a through-hole package. Consider the -30 °C to +80 °C operating temperature range to ensure suitability for the intended environmental conditions. Verify that the input voltage exceeds the minimum dropout requirement for the desired load current. Compare against similar L78 series devices if higher current or different packaging options are needed.

Part Context

This regulator belongs to the L78LR family of three-terminal positive voltage regulators produced by onsemi. These devices are engineered for general-purpose linear regulation tasks where simplicity and reliability are prioritized. The L78LR series typically offers integrated protection features, making them suitable for embedded systems and industrial control applications requiring stable DC voltage conversion from higher input sources.

Replacement Considerations

Consult official cross-reference guides for compatible alternatives. Generic equivalents may exist but require verification of pinout compatibility and thermal performance characteristics to ensure seamless integration without redesigning the host circuit board.
