Analog Devices ADP3335
The ADP3335 is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3335 operates with an input voltage range of 2.6 V to 12 V and delivers a continuous load current up to 500 mA. The ADP3335 stands out from conventional LDOs with the lowest thermal resistance of any MSOP-8 package and an enhanced process that enables it to offer performance advantages beyond its competition.FEATURES
High Accuracy Over Line and Load: ؎ 0.9% @ 25؇ C, ؎1.8% Over Temperature Ultralow Dropout Voltage: 200 mV (Typ) @ 500 mA Requires Only CO = 1.0●F for Stability anyCAP = Stable with Any Type of Capacitor (Including MLCC) Current and Thermal Limiting Low Noise Low Shutdown Current: < 1.0
