Picture 55 is linear voltage regulating circuit of LTC1422.When the input voltage Ui is added to the circuit,feet 2 of LTC1422 is high potential and feet 6 is low potential and the absorbing current is 10mA.At the time,VT1 stops and the output U。is zero.The phase input end (feet 1) voltage in LTC1422 comparator is zero.The output voltage in the comparator is lower than 1.232V reference voltage,thus feet 5 remains low PWL.After a timing cycle,the feet 6 of LTC1422 provides 1OμA for VT1.12V voltage is connected to feet 6 via R1 and it charges C1 with 1.2mA current via R2.R2 and C1 drops slowly and VT1 gate rises to limit impulsing current.
