OPEN-LOOP TEST CIRCUIT

High peak current associated with capacity loads necessitate careful grounding techniques. Timing and bypass

capacitors should be connected close to pin5 in single point GND.

UNDER-VOLTAGE LOCKOUT

During Under-Voltage Lockout, the output driver is biased to a high impedance state. Pin 6 should be shunt to

GND with a bleeder resistor to prevent activing the power switch with output leakage currents.

ERROR AMPLIFIER CONFIGURATION

Error amplifier can source or sink up to 0.5mA
