AP1117

ATC AP1117 Analog Technology, 1A Low Dropout Positive Adjustable or Fixed-Mode Regulator „ Features 1.4V maximum dropout at full load current Fast transient response Output current limiting Built-in thermal shutdown Packages: SOT223, TO252, TO220, SOT89 Good noise rejection 3-Terminal Adjustable or Fixed 1.5V, 1.8V,2.5V, 3.3V, 5.0V „ Applications PC peripheral Communication „ General Description AP1117 is a low dropout positive adjustable or fixed-mode regulator with minimum of 1A 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. AP1117 is also well suited for other applications such as VGA cards. AP1117 is guaranteed to have <1.3V dropout at full load current making it ideal to provide well regulated outputs of 1.25 to 5.0 with 6.3 to 12V input supply. „ Ordering Information AP 1117 X XX X Low Dropout Regulator Package E : SOT223-3L D : TO252-3L T : TO220-3L Y : SOT89-3L Vout Packing Blank : ADJ Blank : Tube 15 : 1.5V A : Taping 18 : 1.8V 25 : 2.5V 33 : 3.3V 50 : 5.0V „ Typical Circuit 5V C1 100uF 5V C1 100uF Vin Vout GND Tab is Vout 3.3V/1A C2 100uF ( 5V/3.3V fixed output ) Vin Vout Adj Tab is Vout R1 121Ω R2 121Ω Vo 2.5V/1A C2 100uF ( 5V/2.5V ADJ output ) Note: Vo = VREF ∗ (1+ R2 R1 ) This datasheet contains new product information.
