Figure 15. Typical Application 2 of AH9280 (Note 3)  
Note 3:  
1. D1 is an ordinary diode used to filter the noise from VCC and protect IC if VCC and GND are plugged  
reversed.  
2. R1=47typical.  
3. C1 =2.2µF typical, electrolytic capacitors are better. They should be fine tuned based on system design.  
4. ZD1 and ZD2 breakdown voltage are 35V.
