DescriptionThe FAN2504/05 family of micropower low-dropout voltage regulators utilize CMOS technology to offer a new level of cost-effective performance in GSM and TDMA cellular handsets, Laptop and Notebook portable computers, and other portable 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 FAN2504/05 family of products offer significant improvements over older BiCMOS designs and are pin-compatible with many popular devices. The output is thermally protected against overload.
The FAN2504 and FAN2505 devices are distinguished by the assignment of pin 4:
FAN2504: pin 4 ADJ, allowing the user to adjust the output voltage over a wide range using an external voltage divider.
FAN2504-XX: pin 4 BYP, to which a bypass capacitor may be connected for optimal noise performance. Output voltage is fixed, indicated by the suffix XX.
FAN2505-XX: pin 4 ERR, a flag which indicates that the output voltage has dropped below the specified minimum due to a fault condition.
The standard fixed output voltages available are 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 3.0V, and 3.3V. Custom output voltage are also available: please contact your local Fairchild Sales Office for information.
