l Low Temperature Coefficient
The AME8845 family of linear regulators feature low
quiescent current (100µA typ.) with low dropout voltage,
making them ideal for battery applications. It is available
in TO-252, SOT-223, TO-263 and TO-220 packages. The
space-efficient TO-252, SOT-223 package is attractive for
"Pocket" and "Hand Held" applications.
Output voltages are set at the factory and trimmed to
1.5% accuracy.
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the
"Worst" of operating conditions.
The AME8845 is stable with an output capacitance of
2.2µF or greater.
