Pinout

PIN FUNCTION DESCRIPTIONS
Pin	Name	Function
1	OUT	Output of the Regulator. Bypass to ground with a 0.47 mF or larger capacitor.
2	IN	Regulator Input.
3	ERR	Output that goes low to indicate that the output is about to go out of regulation.
4	GND	Ground Pin
5	NR	Noise Reduction Pin. Used for further reduction of output noise (see text for detail). No connection if not used.
6	SD	Active Low Shutdown Pin.Connect to ground to disable the regulator output. When shutdown is not used, this pin should be connected to the input pin.

Description

The ADP3330 is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The product operates with an input voltage range of 2.9 V to 12 V and delivers a load current up to 200 mA. The ADP3330 stands out from the conventional LDOs with a novel architecture and an enhanced process that enables it to offer performance advantages and higher output current than its competition. Its patented design requires only a 0.47 mF output capacitor for stability. This device is insensitive to output capacitor Equivalent Series Resistance (ESR), and is stable with any good quality capacitor, including ceramic (MLCC) types for space-restricted applications. The product achieves exceptional accuracy of ±0.7% at room temperature and ±1.4% over temperature, line and load variations. The dropout voltage of the ADP3330 is only 140 mV (typical) at 200 mA. This device also includes a safety current limit, thermal overload protection and a shutdown feature. In shutdown mode, the ground current is reduced to less than 2 mA. The ADP3330 has ultralow quiescent current 34 mA (typ) in light load situations.
