AAT3215
150mA CMOS High Performance LDO
8
3215.2006.05.1.6
Functional Description
The AAT3215 is intended for LDO regulator appli-
cations where output current load requirements
range from no load to 150mA.
The advanced circuit design of the AAT3215 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. This bypass capacitor
will also enhance PSRR behavior. The two com-
bined characteristics of low noise and high PSRR
make the AAT3215 a truly high performance LDO
regulator especially well suited for circuit applica-
tions which are sensitive to their power source.
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 shut down the
LDO regulator for power conservation in portable
products. The enable circuit has an additional output
capacitor discharge circuit to assure sharp applica-
tion 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
AAT3215 a comprehensive safety system during
extreme adverse operating conditions. Device
power dissipation is limited to the package type
and thermal dissipation properties. Refer to the
Thermal Considerations section of this datasheet
for details on device operation at maximum output
current loads.
