AP1186 1.5A Ultra Low Dropout Positive Adjustable or Fixed-mode Regulator 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 complexity 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 + 470uF + Vin Vctrl Vout GND Vsense 5 4 3 2 1 5V 470uF 2.5V/1.5A + 470uF This datasheet contains new product information.

(GND only for fixed mode) This pin is the positive side of the reference that allows remote load sensing to achieve excellent load regulation. A minimum of 10uF capacitor must be connected from this pin to ground to insure stability. The input of the 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 higher than Vout in order for the device to regulate. This pin is the supply pin for the internal control circuit as well as the base drive for the pass transistor. This pin must always by higher than the Vout pin in order the device to regulate. A minimum of 100uF capacitor must be connected from this pin to ground to insure stability. Not used. The output of the regulator. A minimum of 100uF capacitor must be connected from this pin to ground to insure stability.
