FAN2534 Overview
The FAN2534/FAN2535 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 puters, and other portable devices. Proprietary design technics ensure high ripple rejection.
FAN2534 Key Features
- 70dB Ripple rejection ( >45dB up to 1MHz) 150µsec Power On Time 150µsec Enable Time Low noise
- 50µVrms Enable optimized for CDMA time slices 180 mV dropout voltage at 150 mA Enable/Shutdown Control Enable time indep
FAN2534 Applications
- 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 fixed, as specified by the suffix XX. FAN2535-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
