General Description
AP1184 is a 4A regulator with extremely low dropout voltage.
This product is specifically designed to provide well regulated
supply for applications requiring 2.8V or lower voltages from 3.3V
ATX power supplies where high efficiency of the switch can be
achieved without the cost and complexity associated with
switching regulator. One such application is the new graphic
chipsets that requires anywhere from 2.4V to 2.7V supply.

Functional Descriptions
Introduction
The AP1184 regulator is a 5 terminal device designed specifically to provide extremely low dropout voltages comparable to the
PNP type without the disadvantage of the extra power dissipation due to the base current associated with PNP regulators. This is done
by bringing out the control pin of the regulator that provides the base current to the power NPN and connecting it to a voltage that is
greater than the voltage present at the
V
in
pin. This flexibility makes the AP1184 ideal for applications where dual inputs are available
such as a computer motherboard with an ATX style power supply that provides 5V and 3.3V to the board. One such application is the
new graphic chip sets that require anywhere from 2.4V to 2.7V supply. The AP1184 can easily be programmed with the addition of two
external resistors to any voltages within the range of 1.25V to 15.5V. Another major requirement of these graphic chips is the need to
switch the load current from zero to several amps in tens of nanoseconds at the processor pins, which translates to an approximately 300
to 500ns of current step at the regulator. In addition, the output voltage tolerances are also extremely tight and they include the transient
response as part of the specification.
The AP1184 is specifically designed to meet the fast current transient needs as well as providing an accurate initial voltage,
reducing the overall system cost with the need for fewer number of output capacitors. Another feature of the device is its true remote
sensing capability that allows accurate voltage setting at the load rather than at the device.
Output Voltage Setting
The AP1184-ADJ can be programmed to any voltages in the range of 1.25V to 15.5V with the addition of R1 and R2 external
resistors according to the following formula:
