AAT3216
150mA MicroPower LDO with PowerOK

3216.2004.01.0.94
Functional Description
The AAT3216 is intended for LDO regulator appli-
cations where output current load requirements
range from no load to 150mA.
The advanced circuit design of the AAT3216 pro-
vides excellent transient response and fast turn-on
ability. The LDO regulator output has been specif-
ically 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 AAT3216 has an integrated Power-OK com-
parator which indicates when the output is out of
regulation.
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
AAT3216 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 discussion in the section for
details on device operation at maximum output cur-
rent loads.
