GENERAL DESCRIPTION  
TYPICAL OPERATING CIRCUIT  
The ADP667 is a low-dropout precision voltage regulator that  
can supply up to 250 mA output current. It can be used to give  
a fixed +5 V output with no additional external components or  
can be adjusted from +1.3 V to +16 V using two external resis-  
tors. Fixed or adjustable operation is automatically selected via  
the SET input. The low quiescent current (20 µA) in conjunc-  
tion with the standby or shutdown mode (0.2 µA) makes this  
device especially suitable for battery powered systems. The  
dropout voltage when supplying 100 µA is only 5 mV allowing  
operation with minimal headroom and prolonging the battery  
useful life. At higher output current levels the dropout remains  
low increasing to just 150 mV when supplying 200 mA. A wide  
input voltage range from 3.5 V to 16.5 V is allowable.

Additional features include a dropout detector and a low supply/  
battery monitoring comparator. The dropout detector can be  
used to signal loss of regulation, while the low battery detector  
can be used to monitor the input supply voltage.
