The APL5332 is a precise CMOS LDO with source
sink and output selection functions. The APL5332
offers 2% output accuracy. The APL5332 integrates
with two power mosfets to source and sink current
as well as current and thermal limit into a single chip.
The output voltage can be 1.225V or 1.45V by BS pin
selection, and also can be adjusted by an external
resistor divider connected to FB pin.
The APL5332 also works with low-ESR output
capacitors, reducing the amount of board space nec-
essary for power applications.
The APL5332 key features include current-limit, ther-
mal shutdown, and fast transient response. A com-
pact package TO-252-5 for power consumption
purpose, and SOP-8 and SOP-8-P for space saving
purpose.
