TEXAS INSTRUMENTS Fixed LDO Voltage Regulator, 1A, SOT-223-3 - 7.5V 3.3V

The TEXAS INSTRUMENTS Fixed LDO Voltage Regulator is a low dropout positive voltage regulator designed to deliver a stable and reliable output. This component is capable of sourcing 1A of output current with a typical dropout voltage of 500mV, ensuring efficient operation even when the input voltage is close to the output voltage. The device incorporates a quiescent current reduction circuit that minimizes ground current when the input-to-output differential exceeds approximately 3V, making it an energy-efficient choice for power-sensitive applications.

Engineered for robustness, this regulator is specifically designed for vehicular applications, featuring built-in protection against reverse battery installations and 2-battery jumps. The output voltage is trimmed before assembly, ensuring high accuracy and consistency. Additional features include an internal short-circuit current limit, mirror image insertion protection, and P+ product enhancement testing. The component is also a green product, free from antimony and bromine, meeting modern environmental standards.

Key Features:

• Fixed output voltage of 12V
• Wide input voltage range from 0V to 26V
• Maximum output current of 1A
• Low dropout voltage of 500mV (typical)
• Reverse battery protection for automotive use
• Internal short-circuit current limit
• Surface mount package (SOT-223-3) with 3 pins
• Operating temperature range from -40°C to 85°C

This regulator is ideal for industrial and power management applications where a stable, fixed voltage supply is required. Its compact SOT-223-3 package allows for easy integration into space-constrained designs, while its robust protection features ensure long-term reliability in demanding environments.
