The ADP3300 stands out from conventional LDOs with a novel architecture and an enhanced process. Its patented design requires only a 0.47 F ON OFF output capacitor for stability. This device is stable with any capacitor, regardless of its ESR (Equivalent Series Resistance) SD GND value, including ceramic types (MLCC) for space restricted appli- Figure 1.

Other features include shutdown and ture, line and load variations. The dropout voltage of the optional noise reduction capabilities. The ADP330x anyCAP LDO ADP3300 is only 80 mV (typical) at 50 mA. family offers a wide range of output voltages and output current The ADP3300 operates with a wide input voltage range from levels from 50 mA to 200 mA: 3.0 V to 12 V and delivers a load current in excess of 50 mA. ADP3301 (100 mA) It features an error flag that signals when the device is about to lose regulation or when the short circuit or thermal overload ADP3303 (200 mA) anyCAP is a registered trademark of Analog Devices Inc.
