L7915ACD2T-TR

Overview

The L7915ACD2T-TR is a three-terminal negative linear voltage regulator from the L79xxC series, manufactured by STMicroelectronics. It provides a fixed output voltage of -15 V with a maximum output current capability of 1.5 A. The device is housed in a D²PAK (TO-263) surface-mount package and supports a maximum input voltage of -35 V. Internal protections include thermal overload shutdown, short-circuit protection, and safe operating area (SOA) protection for the output transistor.

Feature Summary

Provides local on-card regulation to eliminate distribution problems associated with single-point regulation.
Includes internal thermal overload protection and short-circuit protection for enhanced reliability.
Features output transition SOA protection to prevent damage during high-current operation.

Applications

Split power supply systems requiring negative voltage rails.
Local on-card voltage regulation for electronic circuits.
General-purpose negative voltage regulation in industrial equipment.

Procurement Notes

Verify the specific suffix 'AC' against official datasheets to confirm temperature grade and performance specifications. Confirm package type compatibility with PCB footprint requirements. Check component availability status as manufacturing lifecycles may change. Ensure adequate heat sinking is designed into the application to support the rated current output.

Selection Notes

Select this component when a fixed -15 V negative rail is required in a surface-mount design. Compare against the positive L78xx series for matched split-supply applications. Evaluate thermal management needs based on the input-output voltage differential and load current. Consider the D²PAK package for its balance of current handling and mounting density.

Part Context

This part belongs to the L79xxC family of three-terminal negative regulators. The series offers various fixed output voltages including -5 V, -8 V, -12 V, and -15 V. These devices are designed to complement the L78xx positive regulator series, facilitating the creation of symmetric dual-polarity power supplies for analog and digital circuitry.
