OT1103bj: Low Dropout Linear Regulatorldo5

The OT1103bj 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 designed for Austriamicrosystems high voltage AMSH18 0.18µ process.

Available customizations include specific output voltage, or digitally trimmed output voltage.
