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 dis-
cussion in the section for details on device opera-
tion 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 ESR
ceramic capacitors. However, the design will allow
for operation over a wide range of capacitor types.
The device enable circuit is provided to shutdown
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 give the
AAT3236 a comprehensive safety system during
extreme adverse operating conditions.
