AAT3244 EVAL: 300mA Adjustable Dual
CMOS Low Voltage LDO Linear Regulator
Test: POK Output Response
1. Configure the specified test equipment as shown in Figure 7.
2. Enable dual LDO by setting JP1 and JP3 to the ‘ON’ position, as shown in Figure 2. Connect both inputs
of UUT to V_CC by JP2 and JP4 as shown in Figure 2.
3. Use Line Transient Response board to generate the step input voltage supply.
4. Adjust the power supplies while monitoring V_IN (AC coupling), V_OUT ( AC coupling) and POK (AC coupling)
on the oscilloscope.
