The RN5RG Series are voltage regulator ICs with an external power transistor with high output voltage accu-
These ICs are suitable for constructing regulators with ultra-low dropout voltage and an output current in the
Furthermore, these ICs have a chip enable function, so that the supply current on standby can be minimized.
Since the package for these ICs are SOT-23-5 (Mini-mold) package, high density mounting of the ICs
