OT1102bh: Low Dropout Linear Regulatorldo2

The OT1102bh is a 150mA CMOS low dropout regulator designed for use in a wide variety of mixed signal device applications.

The base design is implemented with lambda-based sizing and portable layout constructs for maximum ease of process porting. This version is ported to the Austriamicrosystems AMSC35 0.35u process.
