Abstract - Low dropout voltage regulators @DO) are widely used in portable communication products such as cellular phones, pagers, and laptops. In this paper, we present a wide range load (100mA) LDO designed with 0.25pm CMOS process. By using a fast transient loop, we obtained high performance in transient response and output stability. Due to the improved transient response, the value of the output capacitor can be decreased. This allows us to integrate the capacitor within the LDO chip. Additional benefit of this approach is that we eliminate the equivalent series resistance. Therefore, the system stability is independent of it.
