Description

The LT3092IST#WTRPBF is a precision low-dropout (LDO) linear voltage regulator manufactured by Analog Devices. It is designed to provide a stable output voltage with a very low dropout voltage, making it ideal for battery-powered applications. The device can deliver a maximum output current of 1A and features an adjustable output voltage range from 0.5V to 15V, set by external resistors.
Key features include a low output noise, high power supply rejection ratio (PSRR), and thermal protection, which enhances reliability. The LT3092 also includes an internal reference voltage for improved accuracy. Its compact 3mm x 3mm 8-lead DFN (dual flat no-lead) package makes it suitable for space-constrained designs.
Overall, the LT3092IST#WTRPBF is widely used in applications like portable electronics, RF systems, and precision analog circuits, where clean and stable voltage is critical.

Features
