When chattering occurs at startup input, LDO output will be abnormal.
Phenomenon 1 Vin = Vout
Phenomenon 2 The voltage is not set. And VADJ voltage is not 1.2 V
However, even if Vin is changed, Vout becomes the previous voltage.
Load is 1 to 2 mA and Max 20 mA.
Even if it is enabled and delays startup, it appears.
Cin, Cout is 2.2 uF.
The incidence is about 10%
Chattering occurs because of the use of the Toggle switch..
Although using ROHM LDO in parallel, output abnormality does not occur there.
How does chattering affect it?
