Part Number: LM320-N Other Parts Discussed in Thread: LM340 , LM2990 We are measuring 3mV of Output Noise Voltage on the LM320T-15 Negative Fixed Voltage Regulator instead of the 400uV suggested in the datasheet.
As you can see, this is a bipolar power…
Part Number: LM320-N LM320T-15/NOPB:
What is the tin thickness on the leads for this part (approximately)?
Was the tin plating heated after deposition? (Annealed, fused, none)
Describe your +/- voltage sources that you are going to connect to the inputs of the + and - regulators, and how much current is needed.
If your inputs are from full-wave rectifiers then there will be lots of 120Hz ripple and the two 1000uF (in parallel…
