FAN2514, FAN2515  
200 mA CMOS LDO Regulators  
with Fast Start Enable  
wide variety of external capacitors, and the compact SOT23-5  
surface-mount package. In addition, the FAN2514/15 family  
offer the fast power-cycle time required in CDMA handset  
applications. The products offer significant improvements  
over older BiCMOS designs and are pin-compatible with  
many popular devices. The output is thermally protected  
against overload.  
Features  
• Ultra Low Power Consumption  
• Enable optimized for CDMA time phases  
• 200 mV dropout voltage at 200 mA  
• 50 µA ground current at 200 mA  
• Enable/Shutdown Control  
• SOT23-5 package  
• Thermal limiting  
• 300 mA peak current  
The FAN2514 and FAN2515 devices are distinguished by  
the assignment of pin 4:  
FAN2514: pin 4 – ADJ, allowing the user to adjust the  
output voltage over a wide range using an external voltage  
divider.  
Applications  
• Cellular Phones and accessories  
• PDAs  
• Portable cameras and video recorders  
• Laptop, notebook and palmtop computers  
FAN2514-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.  
Description  
FAN2515-XX: pin 4 – ERR, a flag which indicates that the  
output voltage has dropped below the specified minimum  
due to a fault condition.  
The FAN2514/15 family of micropower low-dropout voltage  
regulators utilize CMOS technology to offer a new level of  
cost-effective performance in GSM, TDMA, and CDMA  
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  
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.
