| Abstract: | An enable and over-temperature protection circuit for LDO regulator is presented in this paper. The circuit is introduced to shut down the chip whenever the operation temperature is too high tO protect the chip to be damaged effectively. The simulation results by using Hynix 0.5 um CMOS process and Hspice show that the specifications are satisfied and the performances are excellent. |
