The ADP3302 contains two fully independent 100 mA regulators with separate shutdown and merged error outputs. It features 1.4% overall output accuracy and very low, 120 mV typical, dropout voltage. The ADP3302 has a wide input voltage range from ؉3 V to ؉12 V. It features an error flag that signals when either of the two regulators is about to lose regulation. It has short circuit current protection as well as thermal shutdown. The ADP3302’s enhanced lead frame design allows for a maximum power dissipation of 630 mW @ +70°C ambient temperature and 1.0 W at room temperature without any external heat sink. anyCAP™ is a trademark of Analog Devices, Inc.
