B3
drain of a DMOS. B3 connects to the base of an external PNP pass transistor to form a
positive linear regulator.
Analog Gain Block Feedback Input (Regulator 3). Connect to a resistive-divider

B5
drain of a P-channel MOSFET. B5 connects to the base of an external NPN pass
transistor to form a negative linear regulator.
Analog Gain Block Feedback Input (Regulator 5). Connect to a resistive-divider

FB5
between the negative linear regulator ’ s output and a positive reference voltage,
typically one of the positive linear regulator outputs, to adjust the output voltage. The
feedback set point is at GND.
Dual-Mode Current-Limit Adjustment Input. Connect to VL for the default 250mV
current-limit threshold. In adjustable mode, the current-limit threshold voltage is 1/5 th

ILIM
the voltage present at ILIM. Connect to a resistive-divider between VL and GND to
adjust V ILIM between 500mV and 2.5V. The logic threshold for switchover to the 250mV
default value is approximately VL - 1V.
