NOTE: 1. C1 is required only if regulator is separated from rectifier filter.
2. Both C1 and C2 should be low E.S.R. types such as solid
tantalum. If aluminum electrolytics are used, at least 10 times
values shown should be selected.
3. If large output capacities are used, the regulators must be
protected from momentary input shorts. A high current diode
NOTE: C3 optional for improved transient response and ripple rejec
