AP1117 1A Low Dropout Positive Adjustable or Fixed-Mode Regulator Features 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 lower than 1.4V dropout at full load current making it ideal to provide well-regulated outputs of 1.25 to 5.0 with 6.4V to 12V input supply. - 1.4V maximum dropout at full load current - Fast transient response - Output current limiting - Built-in thermal shutdown - Packages: SOT223, TO263, TO252, TO220, SOT89 - Good noise rejection - 3-Terminal Adjustable or Fixed 1.5V, 1.8V, 1.9V, 2.5V, 3.3V, 5.0V Applications - PC peripheral - Communication Ordering Information AP 1117 X XX X X Package Low Dropout Regulator E : SOT223-3L K : TO263-3L D : TO252-3L T : TO220-3L Y : SOT89-3L Vout Blank : ADJ Blank : Normal 15 : 1.5V L : Lead Free Package 18 : 1.8V 19: 1.9V 25 : 2.5V 33 : 3.3V 50 : 5.0V Typical Circuit 5V 5V Vin Vin GND Blank : Tube A : Taping C1 100uF C1 100uF Vout Packing Lead Free Vo Vout 3.3V/1A C2 100uF Adj Tab is Vout R1 121 Ω R2 121 Ω 2.5V/1A C2 100uF Tab is Vout ( 5V/3.3V fixed output ) ( 5V/2.5V ADJ output ) Note: Vo = VREF ∗ (1+ R2 ) R1 This datasheet contains new product information.

(Ground only for Fixed-Mode) Vout O 2 The output of the regulator. A minimum of 10uF capacitor (0.15Ω ≤ ESR ≤ 20Ω) must be connected from this pin to ground to insure stability. 3 The input pin of regulator. Typically a large storage capacitor (0.15Ω ≤ ESR ≤ 20Ω) 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 1.3V higher than Vout in order for the device to regulate properly.

Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from the package. Note2: Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the difference between input and output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range. Note3: Quiescent current is defined as the minimum output current required in maintaining regulation. At 12V input/output differential the device is guaranteed to regulate if the output current is greater than 10mA.
