CMOS 트랜지스터로 구성된 온도 보상된 LDO Regulator 설계

A new temperature compensation LDO (low drop out) regulator configured CMOS transistors was designed. The proposed regulator circuit is consist of temperature compensation band gap reference and LDO. The simulation results that the proposed regulator has output voltage of 1.5V from 2.1V to 5.5V of supply voltage and temperature coefficient of 250ppm/℃ form ~ 20℃ to 140℃. The designed regulator for circuit simulation was used as the Magna/Hynix 0.35㎛ process and supply voltage was 5V.
