Voltage regulation is vital in a wide range of practical applications including communications, computing and other electric circuits, and specialized devices such as the L9468N from STMicroelectronics are ideally suited for many of these. The L9468N is a low-dropout (LDO) three-terminal voltage regulator, an integrated circuit that offers internal output voltage stabilization and a series of other features that make it an ideal choice for modern and automated systems. In this article, we\'ll take a closer look at the L9468N and its application fields, as well as its operating principle and functionality.

What is a LDO?

A Low-Dropout (LDO) regulator is a type of linear voltage regulator that functions as an electronic load, drawing current from an input source and converting it into a constant output voltage with minimal “drop-out” voltage. A linear regulator such as the L9468N also has the added benefit of combining low power dissipation and low noise operation. LDO regulators are used in a wide variety of applications, from providing voltage regulation in automotive, industrial and other power-sensitive environment to powering digital logic in computers and other electronic equipment.

Benefits of L9468N

STMicroelectronics’s L9468N is a low-dropout three-terminal voltage regulator that provides a regulated output voltage of 3.3 V from an input voltage of 3.3 V to 5.5 V. The device has a typical noise of 6 mV RMS and can provide currents up to 100 mA. Its low power dissipation allows it to be used without needing an external heatsink, while its over-current and overtemperature protection make it a safe choice for industrial and medical applications. With high-accuracy output voltage and high-precision load current sensing, it is also suitable for use in precision instrumentation.
