Output Capacitor Selection (Negative Shunt Regulator)
SLVS976 – SEPTEMBER 2009.......................................................................................................................................................................................... www.ti.com
Vss is a shunt regulator that regulates the non-addressed TFT pixels to the programmed voltage. The pulldown
resistor R11 connected to VOFFE is required to provide accurate no load current regulation. A minimum current of
50
A through the feedback divider provides good accuracy. Be aware of the negative value of V
ss for the
calculations.
If a discharge resistor Rdis at the VSS output is used to discharge the VSS node faster, the pull down resistor R11
connected to VOFFE must be calculated by following formula to achieve the programmed output voltage at VSS. A
smaller resistor to the calculated one must be used. For example for VSS = -7.5V, VOFFE = -11V and Rdis = 12k
the calculated R11 = 4.98k
and the resistor values 4.7k, 4.3k, and 4.0k can be used.

For the best output voltage filtering, low ESR ceramic output capacitors are recommended. One 1
F ceramic
output capacitor with a sufficient voltage rating is suitable for most applications. See Table 15 for output capacitor
selection.
