I think wrong capacitor value may cause the output of a linear voltage regulator to oscillate. Please correct me if I'm wrong.
Is there any rule of thumb for determining the input/output capacitors for linear voltage regulators (e.g. 7805, 7905, 7809, 7909, 7812, 7912, 7815, 7915, 7824, 7924)?
Say I wish to create a regulated +24V DC voltage. I choose a transformer with the following rating:
Input: 0-115V, 0-115V
Output: 0-24V, 0,24V)
If the output of the transformer is connected to a full-bridge rectifier, do you think the output of the rectifier is high enough to guarantee proper the operation of the 7824 (with approximately 2V voltage dropout)?
