I need to control the 'IN' (enable) pin of this LDO Voltage regulator (ADP162) with a microcontroller (MSP430G2553). In the datasheet of the LDO, I couldn't find whether or not it has an internal pull-down resistance.
Is it necessary to put an external one or can you directly connect the GPIO pin of the MSP430 and the EN pin? I really use two LDOs: one to power one LCD and the other LDO to power one RF module. In the data sheet, in figure 39 you can see that the start-up time is almost 1 second, so I think it would give plenty of time for the microcontroller to set the appropriate value on the GPIO pin that controls the EN pin of the LDO.
Therefore, I think it is not necessary to use a pull-down. It is right?
