General Description
AP033 is a low dropout positive fixed-mode
regulator with minimum of 1.5A output current
capability. The product is specifically designed to
provide well-regulated supply for low voltage IC
applications such as high-speed bus termination
and low current 3.3V logic supply. AP033 is
guaranteed to have <1.4V dropout at full load
current making it ideal to provide well regulated
outputs of 3.3V with 4.7V to 12V input supply by
different output voltage.
3-Terminal and Fixed 3.3V
1.4V Maximum Dropout at Full Load Current.
Fast Transient Response.
Built-in Thermal Shutdown.
Output Current Limiting.

Function
The input pin of regulator.
Typically a large storage
capacitor is connected from this
pin to ground to insure that the
input voltage does not sag below
the minimum dropout voltage
during the load transient
response. This pin must always
be 1.4V higher than V

order for the device to regulate
properly.
Ground
The output of the regulator. A
minimum of 10µF capacitor
must be connected from this pin
to ground to insure stability.
