So values are as follows: Jan 25, 2. High voltage adjustable bipolar power supply Posted by coinmaster in forum: Yes, my password is: Normally, no capacitors are needed unless the device is situ.

Trouble with a LMHVT

Further, both line and load regulation are bet- ter than standard fixed regulators. In general cooler is better, but semiconductors can take pretty high temperatures, like C on the die, but its everything around it that suffers PCBs can degrade over long periods if cooked, for instance. This is a pretty common circuit, very robust and stable. Jan 25, 4.
