FAN2504: CMOS Low Dropout Voltage Regulator

The FAN2504 of micropower low-dropout voltage regulator utilizes CMOS technology to offer a new level of costeffective performance in GSM and TDMA cellular handsets, laptop and notebook portable computers, and otherportable devices. Features include extremely low power consumption and low shutdown current, low dropout voltage,exceptional loop stability able to accommodate a wide variety of external capacitors, and the compact SOT23-5 surface-mount package. The FAN2504 offers significant improvements over older BiCMOS designs and are pin-compatible with many populardevices. The output is thermally protected against overload.A bypass capacitor may be connected to pin4 for optimal noise performance.
