FOperation notes

(1)

Do not use values other than CT = 0.022

µF for the timing capacitor, and C1 = 10µF for the output capacitor.

(2)

For the output capacitor C1, use a tantalum capacitor with low capacitance variation with temperature, and a static

capacitance tolerance of

±10% or less.

(3)

For the timing capacitor CT, use a film capacitor with low capacitance variation with temperature, a static capaci-

tance tolerance of

±10% or less, and a temperature variation rate of ±2% or less.
