Remark 1.
VOUT(S) specified above is the set output voltage value, and VOUT is the typical value of the actual output voltage.
2.
VDD / VOUT separate type
A step-up operation is performed from VDD = 0.8 V. However, 1.8 V ≤ VDD ≤ 10 V is recommended stabilizing
the output voltage and oscillation frequency. (VDD ≥ 1.8 V must be applied for products with a set value of
less than 1.9 V.)
