GENERAL DESCRIPTION
The ADP3367 is a low-dropout precision voltage regulator that
can supply up to 300 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
resistors. Fixed or adjustable operation can be selected via the
SET input. The low quiescent current (17 A) in conjunction
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 15 mV allowing opera-
tion with minimal headroom thereby prolonging the useful bat-
tery 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 2.5 V to 16.5 V is allowable. Addi-
tional features include a dropout detector and a low supply/bat-
tery 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 ADP3367 is a much improved pin-compatible replacement
for the MAX667. Improvements include lower supply current,
tighter voltage accuracy and superior line and load regulation.
Improved ESD protection (>6000 V) is achieved by advanced
voltage clamping structures. The ADP3367 is specified over the
industrial temperature range –40 C to +85 C and is available in
narrow surface mount (SOIC) packages.

Low-Dropout Linear Voltage Regulator
ADI’s proprietary Thermal Coastline leadframe used in ADP3367AR
packaging, has 30% lower thermal resistance than the standard
leadframes. This improvement in heat flow rate results in lower
die temperature hence improves reliability.
