7.1.9 Operation Beyond Rated Output Current

The TPS7A43-Q1 is rated to 50mA cumulative output current, shared between MID_OUT and OUT; see the Recommended Operating Conditions.

However, the Typical Characteristics section includes some graphs with data that surpass the 50mA rating, extending up to 100mA. Consider this data as nominally accurate. But, if operating close to the current limit, the device can enter current limit or otherwise experience degraded regulation.

If using the device outside of the Recommended Operating Conditions, performance is not confirmed. The decision to use the TPS7A43-Q1 beyond device ratings is solely at the discretion of the user. Reach out to your TI representative for further details.
