SNVSA56B May 2015 – February 2017 LM2776
The LM2776 contains current limit circuitry that protects the device in the event of excessive input current and/or output shorts to ground. The input current is limited to 400 mA (typical at VIN = 5.5 V) when the output is shorted directly to ground. When the LM2776 is current limiting, power dissipation in the device is likely to be quite high. In this event, thermal cycling is expected.
