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.
