Overview
The L7915CD2T-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 an output current capability up to 1.5 A. The device is housed in a D²PAK (TO-263) surface-mount package and operates within a junction temperature range of 0 °C to 150 °C. Maximum ratings include a DC input voltage of -35 V for this output voltage level. Electrical characteristics specify a typical quiescent current of 3 mA and a supply voltage rejection ratio of 60 dB at 120 Hz.
Feature Summary
- Integrated thermal overload protection safeguards against excessive heat generation during operation.
- Built-in short circuit protection limits output current to prevent device damage under fault conditions.
- Output transition SOA protection ensures safe operating area compliance during dynamic load changes.
Applications
- Local on-card regulation for electronic circuits
- Split power supply systems requiring negative voltage rails
- Negative voltage regulation in industrial equipment
Procurement Notes
Verify the specific manufacturer part number L7915CD2T-TR against official STMicroelectronics documentation to confirm compatibility. Ensure that the required D²PAK footprint matches the mechanical data specifications provided in the datasheet. Confirm that the application environment remains within the specified maximum junction temperature and input voltage limits to maintain reliable performance.
Selection Notes
Select this component when a fixed negative voltage rail is required for local regulation. The D²PAK package is suitable for surface-mount assembly where space efficiency is prioritized. Consider the thermal resistance values provided in the datasheet to determine appropriate heat sinking requirements for achieving the full 1.5 A output current capability without exceeding thermal limits.
Part Context
This device belongs to the L79xxC series of negative voltage regulators, which are designed as complements to the L78xx positive regulator series. The series offers multiple fixed output voltages including -5 V, -8 V, -12 V, and -15 V. These regulators are widely used in general-purpose power supply designs due to their robustness and ease of implementation in standard test circuits.
