ADP3336ARMZ-REEL7
a High Accuracy Ultralow IQ, 500 mA anyCAP® Adjustable Low Dropout Regulator ADP3336 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 A 2.6 V to 12 V Supply Range 1.5 V to 10 V Output Range –40؇C to +85؇C Ambient Temperature Range Ultrasmall Thermally-Enhanced 8-Lead MSOP Package FUNCTIONAL BLOCK DIAGRAM Q1 IN ADP3336 THERMAL PROTECTION CC FB SD BANDGAP REF GND ADP3336 OUT OUT IN VIN VOUT OUT R1 IN FB CIN 1F The ADP3336 is a member of the ADP333x family of precision low dropout anyCAP voltage regulators. The ADP3336 operates with an input voltage range of 2.6 V to 12 V and delivers a continuous load current up to 500 mA. The ADP3336 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. Its patented design requires only a 1.0 µF output capacitor for stability. This device is insensitive to output capacitor Equivalent Series Resistance (ESR), and is stable with any good quality capacitor, including ceramic (MLCC) types for spacerestricted applications. The ADP3336 achieves exceptional accuracy of ± 0.9% at room temperature and ± 1.8% over temperature, line, and load. The dropout voltage of the ADP3336 is only 200 mV (typical) at 500 mA. This device also includes a safety current limit, thermal overload protection and a shutdown feature. In shutdown mode, the ground current is reduced to less than 1 µA. The ADP3336 has ultralow quiescent current 80 µA (typical) in light load situations. gm DRIVER APPLICATIONS PCMCIA Card Cellular Phones Camcorders, Cameras Networking Systems, DSL/Cable Modems Cable Set-Top Box MP3/CD Players DSP Supply GENERAL DESCRIPTION OUT SD COUT 1F GND R2 ON OFF Figure 1.
