Sony ACX705AKM

Here are some files and designs that provide the power for the sony ACX705AKM color lcd. There are two designs, one that uses ldo regulators and one that uses the LM317. The unit provides 2 voltages, 3.0V and 4.0V (3.8V) and one current source for the backlight. The backlight are two white leds in series. They need a minimal voltage of 6.3V. The unit has a current source which is adjustable ( a trimmer).The maximim current is 15mA. The idea is that this unit can be used in a 3.3V or 5V environment; It can generate from the 3.3V or 5V the correct voltages and current for the ACX705AKM. A passive data interface (a simple resistor network) and an active data interface is on the board. The interface chip is the SN74LVC245ADW which can run on 3.0V and has 5.0V hard inputs.
