Infineon TLS820F1ELV50: A 50V Low-Dropout Linear Voltage Regulator for Demanding Applications

In the realm of power management, maintaining a stable voltage from a higher, often noisy input source is a fundamental requirement for countless electronic systems. The Infineon TLS820F1ELV50 stands out as a robust and highly specialized solution, engineered to deliver exceptional performance where conventional regulators fall short. As a 50V capable Low-Dropout (LDO) linear regulator, it is designed to operate reliably in harsh electrical environments, providing a clean and precise output voltage.

The defining feature of this LDO is its remarkably wide input voltage range of up to 45V, with an absolute maximum rating of 50V. This high voltage capability makes it an ideal choice for applications such as 24V industrial systems, automotive electronics, and telecommunications infrastructure, where voltage spikes and transients are common. Despite these challenging conditions, the TLS820F1ELV50 ensures a stable output voltage adjustable from 0.8V to 5.0V with a maximum output current of 150mA.

A key advantage of any LDO is its low dropout voltage—the minimum difference required between input and output for regulation. This component excels with a very low dropout voltage of typically 200mV at 100mA load, enhancing efficiency and allowing operation even as the input voltage dips close to the output level. Furthermore, it incorporates critical protection features including over-current protection (OCP), over-temperature shutdown (TSD), and reverse polarity protection, safeguarding both the regulator itself and the sensitive load it powers.

Other notable characteristics include its low quiescent current and excellent line/load regulation, contributing to overall system efficiency and stability. Its compact PG-DSO-8 package is suitable for space-constrained PCB designs.

ICGOOODFIND: The Infineon TLS820F1ELV50 is a superior high-voltage LDO regulator that offers a critical blend of robustness, precision, and integrated protection. It is an exemplary component for designers who need to ensure unwavering power integrity in the most electrically demanding environments.
