8.3.3 Internal Auxiliary LDO

An internal low-dropout regulator is provided to supply external loads, such as digital isolators for the high-side drive signal. It is capable of delivering up to 5 mA to an external load. A bypass capacitor with 0.1 µF typical is recommended. If the digital isolator or the LDO output is not used, LMG341xR150 can start up faster with no bypass LDO capacitor.
