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
