ADP3309 Datasheet (Analog Devices) - 100 mA Low Dropout Linear Regulator

ADP3309, 100 mA Low Dropout Linear Regulator

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 conventional LDOs with a novel architecture and an enhanced process.

ADP3309 Features

* ±1.2% accuracy over line and load regulations @ 25°C Ultralow dropout voltage: 120 mV typical @ 100 mA Requires only COUT = 0.47 μF for stability anyCAP LDOs are stable with all types of capacitors (including MLCC) Current and thermal limiting Low noise Low shutdown current: 1 μA 2.8 V to 12 V suppl
