www.fairchildsemi.com FAN2534/FAN2535 150 mA CMOS LDO Regulator with Fast Start, Enable Features 70dB Ripple rejection ( >45dB up to 1MHz) 150sec Power On Time 150sec Enable Time Low noise - 50Vrms Enable optimized for CDMA time slices 180 mV dropout voltage at 150 mA Enable/Shutdown Control Enable time independent of noise bypass capacitor value SOT23-5 package Thermal limiting 300 mA trimmed current limit low dropout voltage, fast enable required in CDMA handset applications, exceptional loop stability to accommodate a wide variety of external capacitors, and a compact SOT23-5 surface-mount package. These products offer signicant improvements over older Bipolar and CMOS designs and are pin-compatible with many popular devices. The FAN2534 and FAN2535 devices are distinguished by the assignment of pin 4: FAN2534: pin 4 – ADJ, allowing the user to adjust the output voltage over a wide range using an external voltage divider. FAN2534-XX: pin 4 – BYP, to which a bypass capacitor may be connected for optimal noise performance. Output voltage is xed, as specied by the sufx XX. FAN2535-XX: pin 4 – ERR, a ag which indicates that the output voltage has dropped below the specied minimum due to a fault condition. The standard xed output voltages available are 2.6V, 2.85V, and 3.0V . Custom output voltages are also available: please contact your local Fairchild Sales Ofce for information.
