Low-Saturation Three-Pin Regulators with Externally Mounted Power Transistor MM1215 and 1216
Low-Saturation Three-Pin Regulators with Externally Mounted Power Transistor
Monolithic ICs MM1215 and 1216
Outline
These ICs are high-precision, high-voltage stabilized power supply devices which, by employing an externally
mounted power transistor are able to drive loads at large currents. The input/output voltage difference is a low
0.2V, and an internal protection circuit ensures that the devices can be used in a wide range of portable
equipment. Output on/off control is also provided.
