Analog Devices LT3097 | Demoboard EVAL-LT3097

Description

The EVAL-LT3097-AZ evaluation board features the LT3097, a dual 500mA, positive/negative, ultra-low noise, and ultra-high power supply rejection ratio (PSRR), low-dropout (LDO) linear regulator.The EVAL-LT3097-AZ operates over an input voltage range of 3.8 V to 20 V for the positive channel and an input voltage range of -3.8V to -20V for the negative channel. The LT3097 delivers maximum output currents of 500mA. In addition to featuring ultra-low noise and ultra-high PSRR, each channel of the regulator offers programmable power good functionality and a programmable current limit. Current monitoring is also achieved for the positive channel by sensing the ILIMP pin voltage. ILIMN architecture does not allow output current monitoring for the negative channel. The negative channel enable function (ENN/UVN pin) is bidirectional and can be controlled with either a positive or a negative voltage.
