PART OBSOLETE – AP1186 NO ALTERNATE PART 1.5A ULTRA LOW DROPOUT POSITIVE ADJUSTABLE OR FIXED-MODE REGULATOR General Description Features OBSOLETE – PART DISCONTINUED • • • • • • • • 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 a 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 Packages: TO220-5L, TO263-5L Lead Free Finish/RoHS Compliant for Lead Free products (Note 1) Ordering Information AP 1186 Note: X-X Package Vout K5:TO263-5L T5:TO220-5L Blank : Adj 15 : 1.5V 18 : 1.8V 25 : 2.5V 33 : 3.3V 50 : 5.0V X X Lead Free Packing L : Lead Free Package -U : Tube -13: Taping 1.

A minimum of 10uF capacitor must be connected from this pin to ground to insure stability. Adj (GND) A resistor divider from this pin to the Vout pin and ground sets the output voltage. (GND only for fixed mode) Vout O The output of the regulator. A minimum of 100uF capacitor must be connected from this pin to ground to insure stability. Vctrl I 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 for the device to regulate. A minimum of 100uF capacitor must be connected from this pin to ground to insure stability. Vin I 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.
