... IN + CURRENT LIMIT THERMAL SHUTDOWN Figure 2 - Simplified block diagram of the IRU1050. APPLICATION INFORMATION Introduction The IRU1050 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 5.5 V. This regulator ...

... Figure 4 - Schematic showing connection for best load regulation. Stability The IRU1050 requires the use of an output capacitor as part of the frequency compensation in order to make the regulator stable. Typical designs for microprocessor ap- plications use standard electrolytic capacitors with a 3R2 which typical ESR in the range 100mV and an output ADJ capacitance of 500 to 1000mF ...
