Rainbow Electronics MAX15007 User Manual
General Description
The MAX15006/MAX15007 ultra-low quiescent-current
linear regulators are ideal for use in automotive and
battery-operated systems. These devices operate from
an input voltage of 4V to 40V, deliver up to 50mA of output current, and consume only 10µA of quiescent current at no load. The internal p-channel pass device
keeps the quiescent current low even at full load. The
MAX15007 consumes only 3µA current when in shutdown.
The MAX15006A/MAX15007A have a fixed 3.3V output
while the MAX15006B/MAX15007B have a fixed 5V output voltage. The MAX15007 includes an enable input to
turn the device on or off. All devices are short-circuit
protected and include thermal shutdown.
The MAX15006/MAX15007 operate over the -40°C to
+125°C automotive temperature range. These devices
are available in space-saving 3mm x 3mm 6-pin TDFN
and 8-pin SO thermally enhanced packages.
