Description

The LT1963AES8-2.5 is a low-dropout (LDO) voltage regulator designed by Analog Devices (formerly Linear Technology). It provides a stable output voltage of 2.5V with a maximum output current of 1.5A. The device features a low dropout voltage of around 300mV at full load, making it suitable for applications where power efficiency is critical.
Key features include low noise operation (typically 20μVRMS), high power supply rejection ratio (PSRR), and a wide input voltage range from 3V to 20V. The LT1963AES8-2.5 also includes built-in thermal protection and current limiting for enhanced reliability.
Its small footprint (available in an 8-lead SOIC package) makes it suitable for space-constrained designs. It is commonly used in battery-powered devices, RF applications, and precision analog circuits, where a clean and stable power supply is essential.
