GENERAL DESCRIPTION
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 A) in conjunc-
tion with the standby or shutdown mode (0.2 A) makes this
device especially suitable for battery powered systems. The
dropout voltage when supplying 100 A 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.
The ADP667 is a pin-compatible replacement for the MAX667.
It is specified over the industrial temperature range –40 C to
+85 C and is available in an 8-pin DIP and in narrow surface
mount (SOIC) packages.
