A. Use of an input bypass capacitor is recommended if
regulator is far from the filter capacitors.
B. Output voltage is calculated from the equation:
V O = V ref ? 1+ ÷
V O = V ref ? 1+ ÷ - 10 V
? R2 ?
è R1 ?
where: V ref equals the difference between OUTPUT and
ADJUSTMENT voltages ( ≈ 1.25 V).
C. Use of an output capacitor improves transient response,
but is optional.
