PowerSupply (for Bugle) Noise
« on: 13 Aug 2003, 09:06 pm »
An avid customer recently sent me some independently measured test results for the Bugle PowerSupply 1/2-kit.  Noise and ripple on the outputs read about 0.5mV at both zero and full load current.  The negative supply being slightly noisier.

The customer commented: "This is excellent performance and shows when competently designed, the much maligned 78 series regulators are capable of outstanding results."  I would have to agree.  

Although the 78xx and 79xx are not the pinnacle of linear regulator design, they can achieve decent performance.  Quite good for the money.
