9.2. VDDA Power (Low Dropout Regulator)<br />
• 10mA load driving capacity<br />
• Programmable output voltage<br />
• Optional external voltage input<br />
• Low temperature coefficient<br />
VDDA is a voltage source to the ADC, OPAMP and input buffer with low<br />
temperature drift coefficient and programmable linear output regulator. Featuring<br />
programmable output voltage, 10mA load capacity and low temperature drift coefficient<br />
circuit, is perfect in driving small current sensor.<br />
For measuring system that requires shared power supply, users may turn off VDDA<br />
and drive with external input voltage. Set register ENLDO[0] to “1” to enable VDDA.<br />
Select VDDA’s output voltage through register LDO[1:0].<br />

9.3. REFO Reference Voltage<br />
• 200uA load driving capacity<br />
• Programmable output voltage<br />
.<br />
• Optional external voltage input<br />
• Low temperature coefficient<br />
With low temperature drift coefficient and programmable REFO reference voltage<br />
output, it suits your needs for reference voltage for it is the power source of analog<br />
circuit common ground, programmable output voltage, 200uA load capacity and low<br />
temperature drift coefficient circuit design.<br />
