Demonstration circuit 1728A is an adjustable 1.5A negative linear regulator featuring the LT3015. This device supplies up to 1.5A of output current at a typical dropout voltage of 300mV. Operating quiescent current is typically 1.1mA and drops to < 1μA in shutdown. Quiescent current is also well controlled in dropout. In addition to fast transient response, the LT3015 exhibits very low output noise, making it ideal for noise-sensitive applications. A key feature of the LT3015 is the capability to supply a wide output voltage range. The DC1728A can be set to –1.22V, –2.5V, –5.0V, –12.0V, –15.0V, as well as a user selectable value.
