GENERAL DESCRIPTION  
with any good quality capacitor, including ceramic (MLCC)  
The ADP3338 is a member of the ADP33xx family of precision,  
low dropout (LDO), anyCAP voltage regulators. The ADP3338  
operates with an input voltage range of 2.7 V to 8 V and delivers  
a load current up to 1 A. The ADP3338 stands out from  
conventional LDOs with a novel architecture and an enhanced  
process that offers performance advantages and higher output  
current than its competition. Its patented design requires only a  
1 µF output capacitor for stability. This device is insensitive to  
output capacitor equivalent series resistance (ESR), and is stable  
types for space-restricted applications. The ADP3338 achieves  
exceptional accuracy of ±±.8ꢀ at room temperature and ±1.ꢁꢀ  
over temperature, line, and load variations. The dropout voltage  
of the ADP3338 is only 19± mV (typical) at 1 A. The device also  
includes a safety current limit and thermal overload protection.  
The ADP3338 has ultralow quiescent current: 11± µA (typical)  
in light load situations.
