LM2991T P+

The LM2991 uses new circuit design techniques to
provide a low dropout voltage, low quiescent current
and low temperature coefficient precision reference.
The dropout voltage at 1-A load current is typically
0.6 V and an ensured worst-case maximum of 1 V
over the entire operating temperature range. The
quiescent current is typically 1 mA with a 1-A load
current and an input-output voltage differential greater
than 3 V. A unique circuit design of the internal bias
supply limits the quiescent current to only 9 mA
(typical) when the regulator is in the dropout mode
(VOUT ? VIN ? 3 V).
The LM2991 is short-circuit proof, and thermal
shutdown includes hysteresis to enhance the
reliability of the device when inadvertently overloaded
for extended periods. The LM2991 is available in 5-
lead TO-220 and DDPAK/TO-263 packages and is
rated for operation over the automotive temperature
range of ?40?C to 125?C. Mil-Aero versions are also
available.
