All regulator boards were tested for over 12 hours before shipping.

Guaranteed Dropout Voltage at Multiple Current Levels.

The output voltage is 3.3V DC presetted.

Up To 0.5A Output Current, Imax =1.5 / (Vin - Vout), for example, input 10V, output 7V, the maximum output current is 1.5/ (10-7) =0.5A. When Power Dissipation is 1.5watt, the board temperature is 40 centigrade more than environment temperature.

Output Ripple and Noise: Maximum RMS 3mV, Maximum 8mV P-P, @5V, 0.2A output.

Operates Down to 1V Dropout.

0.2% Line Regulation Max.

0.4% Load Regulation Max.

Maximum Input Voltage: 12V.

Suggested Input Voltage: +5~+12V DC.

Output Adjustable Between: +2.5V ~+9V.

Operating EnvironmentTemperatureRange: 0 ~+55℃.

StorageEnvironmentTemperatureRange:-25~+85℃.

Notice:

• GND should be connected to GND or the housing of your instrument.
  
• When linking load, LT1117 is able to regulate output voltage.
  
• Load should be more than 5mA, or the output voltage will be unstable.
  
• Input voltage must be 3V or even higher than output voltage.
  
• If the load is too heavy, the output voltage may be less than expected voltage.

Suggested connection is shown in Figure 1.
