AP1184P

www.DataSheet4U.com AP1184P 4A Ultra Low Dropout Positive Adjustable Regulator „ Feature „ General Description AP1184P 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. 0.7V maximum dropout voltage at 4A load current Built-in Thermal shutdown Output current limiting Adjustable output voltage Fast transient response Good noise rejection Packages: SOP-7L „ Ordering Information AP1184 X X X Low Dropout Regulator Package P7:SOP-7L Lead Free Blank : Normal L : Lead Free Package Packing Blank : Tube A : Taping „ Typical Application 3.3V + 470uF Adj Vsense NC 5V + 470uF Vctrl AP1184P NC Vout 2.5V/4A Vout Vin 121Ω + 121Ω 470uF This datasheet contains new product information.
