Excellent thermal capability, space saving 3 mm 3 mm LFCSP. low dropout anyCAP voltage regulators. The ADP3334 operates with an input voltage range of V to 11 V and delivers a 2. Popular low profile MSOP-8. continuous load current up to 500 mA. The novel anyCAP 3.

3 Traditional thermal enhanced SOIC-8. architecture requires only a very small 1 F output capacitor for stability, and the LDO is insensitive to the capacitor's equivalent ADP3334 . series resistance (ESR). This makes the ADP3334 stable with any IN OUT. capacitor, including ceramic (MLCC) types for space restricted VIN IN OUT VOUT. applications. R1 CNR. CIN COUT.
