(1) VRESET current supplies both DMD and negative 8V LDO.
(2) VOFFSET, VBIAS, and VRESET are designed to supply the DMD and negative 8V LDO only, and should not be connected to additional loads.
(3) The capacitance value of some ceramic capacitor types can diminish drastically depending on the applied DC voltage and temperature. TI recommends X7R dielectric capacitors to minimize capacitance loss over voltage bias and temperatures. Using a higher voltage rated part and/or a larger package size also helps minimize the capacitance reduction at the applied DC voltage. Refer to the DLP5531Q1EVM for suggested components.
(4) Pull down resistors required to meet minimum current requirement.
