GENERAL DESCRIPTION
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. 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 equivalent series resistance (ESR)
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
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.
