2
The ADP3000 is a versatile step-up/step-down switching  
regulator that operates from an input supply voltage of 2 V to  
12 V in step-up mode and up to 30 V in step-down mode.

ADP3000-3.3V  
The ADP3000 operates in Pulse Frequency Mode (PFM) and  
consumes only 500 µA, making it highly suitable for applica-  
tions that require low quiescent current.

The ADP3000 can deliver an output current of 100 mA at  
3 V from a 5 V input in step-down configuration and 180 mA at  
3.3 V from a 2 V input in step-up configuration.

The auxiliary gain amplifier can be used as a low battery detector,  
linear regulator undervoltage lockout or error amplifier.  
Figure 1. Typical Application  
The ADP3000 operates at 400 kHz switching frequency. This  
allows the use of small external components (inductors and  
capacitors), making the device very suitable for space constrained  
designs.
