The LT1963AES8#TRPBF is an LDO (Low Drop Out) voltage regulator and a fast transient 1.5A LDO voltage regulator manufactured by Analog Devices. It features an adjustable output voltage from 0.8V up to 5.5V and current up to 1.5A. It also offers over temperature, over current, and short circuit protection. This fully-integrated low noise regulator has an extremely low drop out voltage and can deliver up to 1.5A of current. It is also capable of providing a fast transient response time, minimizing output voltage uncertainty during load changes. The LT1963AES8#TRPBF is suitable for various applications such as portable electronics, cellular phones, other small form factor applications, and other low voltage regulated designs.
