Analog Devices Inc. ADP3301ARZ-5

Description
The ADP3301 is a high-accuracy, low-dropout linear regulator that offers exceptional stability with any type of capacitor, including ceramic types (MLCC). Its patented design features a noninverting wideband driver and a stage that permits the use of an internal "pole splitting" capacitor to stabilize the feedback loop with a single output capacitor as small as 0.47 uF. This device achieves exceptional accuracy of ±0.8% at room temperature and ±1.4% overall accuracy over temperature, line, and load regulations. The dropout voltage of the ADP3301 is only 100 mV (typical) at 100 mA.
