GENERAL DESCRIPTION  
DRIVER  
R1  
The ADP1073 is part of a family of step-up/step-down switch-  
ing regulators that operates from an input supply voltage of as  
little as 1.0 V. This extremely low input voltage allows the  
ADP1073 to be used in applications requiring use of a single  
cell battery as the primary power source.  
ADP1073-3.3: R1 = 62.1k  
ADP1073-5: R1 = 40k⍀  
ADP1073-12: R1 = 16.3k⍀  
R2  
904k⍀  
GND  
SENSE  
The ADP1073 can be configured to operate in either step-up or  
step-down mode but for input voltages greater than 3 V, the  
ADP1173 is recommended.  
An auxiliary gain amplifier can serve as a low battery detector or  
linear regulator. Quiescent current on the ADP1073-5 is only  
100 µA unloaded, making it ideal for systems where long battery  
life is required.  
The ADP1073 can deliver 40 mA at 5 V from an input voltage  
range as low as 1.25 V, or 10 mA at 5 V from a 1.0 V input.  
Current limiting is available by adding an external resistor.
