I have built my STEPS as per the Tangent web site.
Australia's AC Voltage is 240V.
I had already ordered the 25VA 2X 15V transformer as per Tangent's instructions, by the time Guzzler notified me that the regulator may run a bit hot. I wish to use the STEPS to power an M³ with AD8610 op-amps and thus need the output voltage to be 24V.
The LM317 voltage regulator runs very hot. I am concerned about it overheating the other components. I have insulated it (and used silicone grease) from the heat sink.
My voltages are as follows:
NO LOAD:
test points 1 and 2 - 38V
test points 3 and 5 - 50V
test points 4 and 5 - 24V
M³ connected and powered up:
test points 1 and 2 - 34.7V
test points 3 and 5 - 40.8V
test points 4 and 5 - 24V
Which transfornmer should I use, the 25VA 2X 12V one ?
Is there another way to make the regulator run cooler ??? I realise that it is dropping way too large a voltage. The M³ draws about 0.3A
Should I change my op-amps to OPA627Ap and OPA637AP and run my power supply at 36V? This would make the regulator run cooler ???
