  • Abstract
    A 2.5V capacitor-free CMOS low dropout regulator for powering analog circuits is presented. Stable operation is achieved with or without a large load capacitor by replacing the bulky external output capacitor with an operational amplifier-based active circuit. The regulator provides a 100mA output current and consumes 80muA regardless of the load current.
