Advanced Power Electronics Corp. 1.5A Low Dropout Positive Adjustable or Fixed-Mode Regulator www.DataSheet4U.com AP E1086 „ Features • • • • • „ General Description APE1086 is a low dropout positive adjustable or fixed-mode regulator with minimum of 1.5A output current capability. The product is specifically designed to provide well-regulated supply for low voltage IC applications such as high-speed bus termination and low current 3.3V logic supply. APE1086 is also well suited for other applications such as VGA cards. APE1086 is guaranteed to have <1.4V dropout at full load current making it ideal to provide well-regulated outputs of 1.25V to 5.0V with 4.7 to 12V input supply by different output voltage. 3-Terminal Adjustable or Fixed 1.5V, 1.8V, 2.5V, 3.3V, 5.0V 1.4V Maximum Dropout at Full Load Current Fast Transient Response Built-in Thermal Shutdown Output Current Limiting RoHS Compliant „ Ordering Information APE1086 X X Low Dropout Regulator Package H : TO252-3L S : TO263-3L P : TO220-3L Vout Blank : Adj 15 = 1.5V 18 = 1.8V 25 = 2.5V 33 = 3.3V 50 = 5.0V „ Typical Application 5V to 3.3V Fixed Mode Regulator 5V C1 100uF Vin Vout GND Tab is Vout 3.3V/1.5A C2 100uF Vin Vout Adj Tab is Vout R1 121 Ω R2 121 Ω 5V Adjustable Regulator C1 100uF VOUT=Vref × (1+R2/R1) 2.5V/1.5A C2 100uF Note: Vo = VREF ∗ (1+ R2 ) R1 This datasheet contains new product information.

A minimum of 10uF capacitor must be connected from this pin to ground to insure stability. The input pin of 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 1.4V higher than Vout in order for the device to regulate properly.
