BLOCK DIAGRAM
The IP1621 is an integrated circuit that has triple LDO
regulators and one reset circuit. All the LDO regulators
have their own internal npn power transistors and their
nominal output voltages are 2.67V and 3.4V, respectively.
The reset circuit monitors the status of the regulator input
voltage and outputs the RESET signal. RESET becomes
high after the delay time that is determined by the exter-
nal capacitor at Td pin. The delay time begins to start
after the input voltage reaches above 4.2V.
