The LMS8117AMP-ADJ is a low dropout linear regulator designed for power applications in modern digital systems. This product is cost-effective, efficient and integration-friendly, making it suitable for a wide range of applications.

The LMS8117AMP-ADJ is a low-input voltage (up to 5.5V), low-dropout (300 mV max at 1A when regulated) linear regulator that offers adjustable output voltage over a wide range (2.5V to 10.5V). It is robustly designed to allow a wide input voltage range and is efficient, providing up to 800 mA continuous current capability. This product uses an external R and C that set the output voltage and can be synchronized to an external clock.

Additionally, the product includes integrated reverse-battery protection, internal thermal shutdown and overtemperature protection, ripple rejection (40dB) and line transient suppression features. This product also features integrated power limiting for over-current protection of the load, allowing for a stable power delivery. Finally, the product’s open drain power-good output device allows for the monitoring the output voltage.

LMS8117AMP-ADJ features jitter-free positive voltage regulation for digital and power sensitive applications, making it suitable for a variety of applications such as consumer electronics, computing, telecommunications, automotive and industrial. It is designed for applications that require high precision control. The device has a simple and flexible architecture that enables high performance and low-cost implementations.

The LMS8117AMP-ADJ is an active load-line regulator, which works by maintaining a constant voltage drop between the output of an error amplifier and the output voltage. This voltage drop is determined by a voltage divider consisting of an adjustable resistor (R1) and a resistor (R2). A resistive network then senses the output voltage and adjusts the ratio of the resistors, thereby maintaining the output voltage constant. When the input voltage changes, the voltage difference between the input and the output of the error amplifier changes, causing the output voltage to change. This change is detected by the resistive network and the output voltage is adjusted accordingly.

The LMS8117AMP-ADJ integrates a wide range of features, making it suitable for a wide range of applications. Its precision control, low dropout, wide input voltage range, integrated reverse-battery protection and many other features make it an ideal option for power applications. With its robust design and wide variety of features, the LMS8117AMP-ADJ is an ideal choice for power applications in digital systems.
