... IN + CURRENT LIMIT THERMAL SHUTDOWN Figure 2 - Simplified block diagram of the IRU1117. APPLICATION INFORMATION Introduction The IRU1117 adjustable Low Dropout (LDO) regulator is a three-terminal device which can easily be programmed with the addition of two external resistors to any volt- ages within the range of 1.25 to 5.5V. This regulator only needs 1 ...

... IRU1117 when regulating V 2.85V. The "Extra" voltage means additional power is dissapated in the IRU1117. The diode dissapates some of this additional power, allowing the IRU1117 to run cooler. The steps for selecting the right package with proper board area for heat sinking to keep the junction tem- ...
