DESCRIPTION

The REG1117 is a family of easy-to-use three-terminal

voltage regulators. The family includes a variety of fixed-

and adjustable-voltage versions, two currents (800mA and

1A) and two package types (SOT-223 and DDPAK). See

the chart below for available options.

Output voltage of the adjustable versions is set with two

external resistors. The REG1117 low dropout voltage

allows its use with as little as 1V input-output voltage

differential.

Laser trimming assures excellent output voltage accuracy

without adjustment. An NPN output stage allows output

stage drive to contribute to the load current for maximum

efficiency.

If this occurs at more than 40°C above the maximum expected ambient temperature, then TJ will be less than 125°C during normal operation.

These must be soldered to a circuit board with a substantial amount of copper remaining, as shown in Figure 5. Circuit board traces connecting the tab and the leads should be made as large as practical. The mounting tab of both packages is electrically connected to VOUT.
