AP1086 Datasheet | ANACHIP

Features - - - - - - General Description AP1086 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. AP1086 is also well suited for other applications such as VGA cards. AP1086 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 - Ordering Information AP1086 X X X X Low Dropout Regulator Package D : TO252-3L K : TO263-3L T : TO220-3L Vout Blank : Adj 15 = 1.5V 18 = 1.8V 25 = 2.5V 33 = 3.3V 50 = 5.0V Lead Free Packing Blank : Normal Blank : Tube L : Lead Free Package A : Taping - Typical Application 5V to 3.3V Fixed Mode Regulator 5V C1 100u F Vin Vout GND Tab is Vout 3.3V/1.5A C2 100u F Vin Vout Adj Tab is Vout R1 121 Ω R2 121 Ω 5V Adjustable Regulator C1 100u F VOUT=Vref × (1+R2/R1) 2.5V/1.5A C2 100u F Note: Vo = VREF ∗ (1+ R2 ) R1 This datasheet contains new product information.
