AOZ1117TI-AAL_2

PRELIMINARY AOZ1117 1A Low Dropout Linear Regulator General Description Features The AOZ1117 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. The AOZ1117 is also well suited for other applications such as VGA cards. The AOZ1117 is guaranteed to have lower than 1.4V dropout at full load current making it ideal to provide well-regulated outputs of 1.25V to 5.0V with 2.75V to 14V input supply. ● ● ● ● ● ● ● 1.4V maximum dropout at full load current Fast transient response Output current limiting Built-in thermal shutdown Good noise rejection 3-terminal adjustable or fixed 1.5V, 1.8V, 2.5V, 3.3V, or 5.0V TO252 package Applications ● ● PC peripheral Communication Typical Circuits Fixed Output Example VIN + 5V Adjustable Output Example VIN + 5V VOUT = 3.3V VOUT = 3.3V 3 3 VIN C1 10µF VOUT ADJ/GND VIN VOUT 2 2 ADJ/GND 1 C2 10µF C1 10µF 1 R1 240Ω AOZ1117 C2 10µF R2 390Ω AOZ1117 VOUT = VREF x 1 + R2 R1 VREF = 1.250V Figure 1.

(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. Vin I 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 1.4V higher than Vout in order for the device to regulate properly.
