STMicroelectronics L7805ABD2T-TR Voltage Regulator

The L7805ABD2T-TR from STMicroelectronics is a robust positive voltage regulator designed to deliver a fixed output of 5V with a maximum current of up to 1.5A. This linear voltage regulator is a part of the L78 series, known for their reliability and ease of use. The device is housed in a D2PAK surface-mount package, making it suitable for high-density PCB designs.

Featuring thermal overload protection, safe area protection, and short-circuit protection, the L7805ABD2T-TR ensures the safety and stability of your electronic circuits. These features work together to prevent damage to the device and the circuit it is part of, under extreme conditions. The thermal overload protection automatically shuts down the output if the operating temperature exceeds safe limits, while the safe area protection prevents the IC from operating in an unsafe current-to-voltage condition. The short-circuit protection helps to safeguard the voltage regulator and the load in the event of a direct short.

This voltage regulator has a wide input voltage range, typically from 7V to 35V, which provides flexibility in various applications. Its ability to maintain a stable 5V output across a range of input voltages and load conditions makes it an excellent choice for powering microcontrollers, sensors, and other 5V logic devices in consumer, industrial, and automotive applications.

The L7805ABD2T-TR also boasts a low dropout voltage, which enhances its efficiency and allows it to operate effectively even when the input voltage is close to the output voltage. The low quiescent current draw of the regulator ensures minimal power loss when the device is in standby mode, contributing to energy savings in battery-powered applications.

With its robust design, comprehensive protection features, and reliable performance, the L7805ABD2T-TR from STMicroelectronics is a versatile solution for a wide range of regulated power supply applications. Its surface-mount package allows for efficient use of PCB space, making it a popular choice for compact electronic designs.
