GENERAL DESCRIPTION

120 mV (typical) at 100 mA. This device also includes a current

limit and a shutdown feature. In shutdown mode, the ground

current is reduced to ~1 µA.

The ADP3309 is a member of the ADP330x family of precision

low dropout anyCAP voltage regulators. It is pin-for-pin and

functionally compatible with National’s LP2981, but offers

performance advantages. The ADP3309 stands out from con-

ventional LDOs with a novel architecture and an enhanced

process. Its patented design requires only a 0.47 µF output

capacitor for stability. This device is stable with any type of

capacitor regardless of its ESR (Equivalent Series Resistance)

value, including ceramic types for space restricted applications.

The ADP3309 achieves ±1.2% accuracy at room temperature

and ±2.2% overall accuracy over temperature, line and load

regulations. The dropout voltage of the ADP3309 is only

The ADP3309 operates with a wide input voltage range from

3.0 V to 12 V and delivers a load current in excess of 100 mA.

The ADP3309 anyCAP LDO offers a wide range of output

voltages. For a 50 mA version, refer to the ADP3308 data sheet.
