Note 1: Specifications are 100% production tested at T
Note 2: Since the CHG shunt regulator has a 25Fs delay, the user must limit the voltage to the Absolute Maximum Rating until the
Note 3: LCE mode is entered by pulsing AE high, then pulsing AE low.
Note 4: Since LCE is compared to the REG pin voltage for operation, the low-power regulator cannot be switched off under condi-
