Figure 1 : Error Amp Configuration.
Error amp can source or
sink up to 0.5mA
Figure 2 : UnderVoltage Lockout.
During Under-Voltage Lockout,the outputdriver is
biased to sink minor amounts of current. Pin 6
shouldbe shunted to ground with a bleederresistor
to preventactivatingthe powerswitch with extrane-
ous leakage currents.
