APPLICATION INFORMATION
Detailed Description
The LM8805 consists of a high-precision voltage reference, an error correction circuit, and a current limited
output driver. With good transient responses, output remains stable even during load changes. The SHDN
input enables the output to be turned off, resulting in reduced power consumption.
The LM8805 incorporates both over-temperature and over-current protection.
