Evaluation/Testing
Enabling [Jumper 1 initially in ON position on EN]
1. Turn-Off
With input voltage applied, remove Jumper 1 and re-insert in the OFF position on EN. The output voltage will decay
to zero.
1. Turn-On
With input voltage applied, remove Jumper 1 and re-insert in the ON position on EN. The output voltage will
recover to its nominal DC value of 3.3V.
Load and Line Regulation
1. Enable the AAT1299 by placing Jumper 1 in the ON position on EN, as shown in Figure 2.
2. Turn on the input power supply and set to desired input voltage based on the DC voltmeter.
3. Vary the output load from 0 to 250mA (for a dual AA cell input) and vary the input voltage from 1.0V to V_OUT while
monitoring the output voltage.
