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.
