Product Details
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.
Built-in protection for the positive channel includes reverse-battery protection and reverse current protection. Built-in protection for both channels includes an internal current limit with foldback and a thermal limit with hysteresis.
For full details on the LT3097, refer to the LT3097 datasheet, which must be consulted with the user guide when using the EVAL-LT3097-AZ evaluation board.
The LT3097 of the EVAL-LT3097-AZ features a 22-lead, 6 mm x 3 mm plastic dual-flat no-leads (DFN) package with exposed pads on the bottom side of the IC. Proper board layout is essential for maximum thermal performance.
