Application of ACE605

ACE6051XFM+

Vout=0.6*(1+R1/R2)

Above is adjustable output and below is the fixed 1.8V voltage output circuit

ACE6051XFM+

Notes:

In order to get better dropout and larger output current, keep Ven higher +0.8V or more than Vin , which also result in better

output ripple.

1. in order to have a lower ripple output voltage, pls. add a small capacitor from enable pin to ground

2. pull up enable pin to 3.3V or 5V , the voltage , the better , is higher than vin.

3. the fixed output voltage version is also adjustable via two external resistors, adjust from 0.6V .

4. if enable voltage is same as Vin , the dropout voltage is 1V , if higher than Vin + 0.8V , the dropout voltage can be less

than 0.3V
