... 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 ...
