RC1587T15

Overview

The RC1587T15 is a fixed positive low dropout voltage regulator manufactured by Fairchild Semiconductor. It provides a stable 1.5V output with a maximum current capability of 3A. The device features a dropout voltage of approximately 1.2V at full load, ensuring efficient operation in low-voltage applications. It is housed in a TO-263 (D2PAK) surface-mount package, suitable for automated assembly. The regulator includes internal protection mechanisms such as thermal shutdown and current limiting to safeguard against overload conditions.

Feature Summary

• Fixed 1.5V output voltage for precise power supply requirements
• High current delivery capability up to 3A for demanding loads
• Low dropout characteristic minimizes power dissipation
• Integrated thermal and current protection for enhanced reliability

Applications

• Portable battery-powered equipment requiring stable low voltage
