Overview
Product Details
Demonstration circuit DC2276A is a 1.5A low dropout negative linear regulator featuring the LT3091. This device is designed for applications requiring a negative output voltage, output adjustability from –32V down to 0V, and low dropout voltage. The input voltage range is –1.5V to –36V and the output voltage is jumper selectable and can be set to –1.25V, –2.5V, –5V, –12V or –15V.
The LT3091 features fast transient response, high PSRR and output noise as low as 18µVRMS. A single resistor adjusts the LT3091’s precision programmable current limit. The LT3091’s positive or negative current monitor either sources a current (0.25mA/A) or sinks a current (0.5mA/A) proportional to output current.
