Power Supply to DMD Formatters
Power Voltage generated on Board
On board, 3 LT®1580 7A low dropout regulators are provided to generate the +2.5V for the 3 DMD formatters. The dropout voltage
of this device is 100mV at light loads rising to just 540mV at 7A. To achieve this dropout, a second low current input voltage 1V
greater than the output voltage, is required. The device can also be used as a single supply device where dropout is comparable
to an LT1584. A remote SENSE pin is brought out. This feature virtually eliminates output voltage variations due to load changes.
Typical load regulation, measured at the SENSE pin, for a load current step of 100mA to 7A is less than 1mV. The LT1580 has fast
transient response, equal to the LT1584. On fixed voltage devices, the ADJ pin is brought out. A small capacitor on the ADJ pin
further improves transient response.
