AP1186 Datasheet | Anachip

Feature - - - - - - - - General Description AP1186 is a 1.5A 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 a switcher can be achieved without the cost and plexity associated with switching regulator. One such application is the new graphic chip sets that require anywhere from 2.4V to 2.7V supply. Adjustable or Fixed output voltage 1.5V, 1.8V, 2.5V, 3.3V, 5.0V 0.5V Maximum Dropout voltage at 1.5A Load current Built-in Thermal Shutdown Output Current Limiting Fast transient response Good noise rejection Package : TO220-5L, TO263-5L - Ordering Information AP 1186 X X X X Low Dropout Regulator Package Vout Lead Free Blank : Normal L : Lead Free Package Packing Blank : Tube A : Taping& Reel K5:TO-263-5L Blank : Adj T5:TO-220-5L 15 : 1.5V 18 : 1.8V 25 : 2.5V 33 : 3.3V 50 : 5.0V - Typical Application 3V + 470u F + Vin Vctrl Vout GND Vsense 5 4 3 2 1 5V 470u F 2.5V/1.5A + 470u F This datasheet contains new product information.
