High – voltage – tolerant power supply in a Standard CMOS technology 5V to 3.3V and 5V to 1.8V Linear Voltage Regulator. Based on 0.18µM 3.3V/1.8V Logic process. This power Regulator design provides a 3.3V and 1.8V power supply which is regulated by a 5V supply. The maximum output are 120mA for a 3.3V channel and 60mA for a 1.8V channel.

The Voltage Regulator provides a constant voltage for the given channel.
