Abstract :
A compensation circuit which considered a resistance of a bonding wire for improving a load regulation of a low dropout regulator (LDO) is presented. The circuit is designed a conventional 0.18 mu CMOS process that provides a high performance of a load regulation for a LDO despite of a high load current and a high bonding wire resistance. The proposed circuit is not affected by an input to the LDO and an output voltage setting as well as a variation of temperature and threshold voltages of transistors. The output voltage of the LDO which can be maintained at 0.5% fluctuation when a load current change from 0[mA] to 300[mA] is confirmed by simulation results of HSPICE. This characteristic plays an importance role for the design of LDOs at low output voltage with a high output current.
