FAN2510, FAN2511  
100 mA CMOS LDO Regulators with Fast Start Enable  
wide variety of external capacitors, and the compact SOT23-5  
surface-mount package. In addition, the FAN2510/11 family  
offer the fast power-cycle time required in CDMA handset  
applications. These products offer significant improvements  
over older BiCMOS designs and are pin-compatible with  
many popular devices. The output is thermally protected  
Features  
• Ultra Low Power Consumption  
• Enable optimized for CDMA time slices  
• 100 mV dropout voltage at 100 mA  
• 25 µA ground current at 100 mA  
• Enable/Shutdown Control  
against overload.  
• SOT23-5 package  
• Thermal limiting  
• 300 mA peak current  
The FAN2510 and FAN2511 devices are distinguished by  
the assignment of pin 4:  
FAN2510: 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  
FAN2510-XX: pin 4 – BYP, to which a bypass capacitor  
• Laptop, notebook and palmtop computers  
may be connected for optimal noise performance. Output  
voltage is fixed, indicated by the suffix XX.  
Description  
The FAN2510/11 family of micropower low-dropout voltage  
regulators utilize CMOS technology to offer a new level of  
cost-effective performance in GSM, TDMA, and CDMA  
FAN2511-XX: pin 4 – ERR, a flag which indicates that the  
output voltage has dropped below the specified minimum  
due to a fault condition.  
cellular handsets, Laptop and Notebook portable computers,  
The standard fixed output voltages available are 2.5V, 2.6V,  
and other portable devices. Features include extremely low  
2.7V, 2.8V, 2.85V, 3.0V, and 3.3V. Custom output voltage are  
power consumption and low shutdown current, low dropout
