Note 1

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur Operating ratings indicate conditions the device is intended

to be functional but device parameter specifications may not be guaranteed under these conditions For guaranteed specifications and test conditions see

the Electrical Characteristics

Note 2

The typical junction-ambient thermal resistance of the molded plastic SO(M) package is 155 CW Therefore the maximum current for the buffer and

voltage regulator are limited to the maximum total power dissipation that the package can allow in order to keep the die comfortably below the maximum

operating junction temperature of 125 C

Note 3

The settling time of the Power Buffer is mostly dependent upon the TFT effective series RC load The measurement of the settling time is taken for the

Human Body Model 100 pF and 15 kX Machine Model 0X

Note 5

The precision of the P5V supply determines the output voltage swing precision of the buffer for very small loads The operating range of P5V in this

Note 6

This capacitance is dominated by the ESD protection zeners connected to the SYNC pin

Note 7

It is important to understand that the load current of the low drop-out voltage regulator must not drop below 2 mA Otherwise the internal error

amplifier will not have sufficient drive capability to the large series pass transistor If load requirements from the FPD system is less than 2 mA an external pre-

Note 8

The thermal shutdown mode of the voltage regulator and the system shutdown mode are identical When either of the two functions are enabled two

Note 9

Typical values represent the most likely parametric norm

Note 10

The typical closed loop voltage gain of the low drop-out voltage regulator is 344(107 dB)

Note 11

The minimum load current of the voltage regulator is a specific parameter used to guarantee that the regulated output voltage of the LDO regulator
