BQ27510-G3: internal 2.5V LDO spec check

Jason Lo

Part Number: BQ27510-G3

Assuming power is connected to the REGIN pin on BQ27510-G3, are there any cases where the internal +2.5V LDO turns off? Or does it always stay on? If possible, I would like to use this to power a small microcontroller that would handle I2C comms with the BQ27510-G3.

Hi
The REGIN voltage should be higher than 2.7V to keep the LDO on.
The short circuit current if REG25 output is 250mA. The current consumption of your MCU should be more less than this value

Terry:

Thank you for the response.

So there are no conditions where the LDO will turn off as long as REGIN is greater than +2.5V? Just double-checking since the MSP430 I am connecting to it must never turn off or brownout.

Jason
