Functional Description
The AAT3236 is intended for LDO regulator appli-
cations where output current load requirements
range from no load to 300mA. The AAT3236 is
capable of handling peak output currents up to
500mA. Refer to the Thermal Considerations sec-
tion of this datasheet for details on device operation
at 500mA peak loads.
The advanced circuit design of the AAT3236 pro-
vides excellent input-to-output isolation, which
allows for good power supply ripple rejection char-
acteristics. To optimize for very low output self
noise performance, a bypass capacitor pin has
been provided to decrease noise generated by the
internal voltage reference.
The LDO regulator output has been specifically
optimized to function with low-cost, low-equivalent
series resistance (ESR) ceramic capacitors.
However, the design will allow for operation over a
wide range of capacitor types.
The device enable circuit is provided to shut down
the LDO regulator for power conservation in portable
products. The enable circuit has an additional out-
put capacitor discharge circuit to assure sharp appli-
cation circuit turn-off upon device shutdown.
This LDO regulator has complete short-circuit and
thermal protection. The integral combination of
these two internal protection circuits gives the
AAT3236 a comprehensive safety system during
extreme adverse operating conditions.
