DC to DC--- AP1117D33L (U8/U10)

AP1117 is a low dropout positive adjustable or fixed-mode regulator with 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 18V input supply.

Pin Descriptions

Name I/O Pin # Function

Adj (GND) I 1 A resistor divider from this pin to the Vout pin and ground sets the output voltage.

(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 1.3V higher than Vout in order for the device to regulate

properly.

5. Adjustment Procedure Setting the Timing Mode

Setting the timing mode is important for maximizing the quality of the screen image and minimizing eye strain. The

timing mode consists of the resolution (example 1680 x 1050) and refresh rate (or vertical frequency; example 60

Hz). After setting the timing mode, use the OSD (On-screen Display) controls to adjust the screen image.

For the best picture quality set your LCD display timing mode to:

VESA 1680 x 1050 @ 60Hz.

To set the Timing Mode:

1. Set the resolution: Right-click on the Windows desktop > Properties > Settings > set the resolution.

2. Set the refresh rate: See your graphic card's user guide for instructions.
