Circuit for Increasing Output Voltage

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 electrolytic

capacitors 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

rejection.
