At what point is a source voltage applied to a CE pin?


LDO Linear RegulatorsDC/DC Switching RegulatorsHow to use

It depends on the internal circuit of the products. Some Regulators with a current path between the CE and the VIN may be damaged if a voltage is applied to the CE prior to the VIN.

In the circuit structure shown in Fig. 1, input sequence to the CE and the VIN is free, because there is no current path between them. However, some exceptional LDOs which reset their internal circuits by the CE signal may not operate properly.

In the case of Fig. 2, the IC may be damaged if a large current flows from the CE by input sequence problem. Do not apply voltages to the CE before the VIN.

When the circuit structure between the VIN and CE is uncertain, please contact us.
