... During these fault conditions of the primary regulator the standby regulator will continue to power its load. The SG29055 is the 5 volt, ±5% version of a family of dual regulators with a standby output voltage of 5V. Other high current outputs of 8.2V and 12V are available Also available is the SG29055A which offers an improved output voltage tolerance of ± ...

... ON APPLICATION NOTES The advantages of using a low-dropout regulator such as the SG29055/55A are the need for less “headroom” for full regula- tion, and the inherent reverse polarity protection provided by the PNP output device. A typical NPN regulator design requires an input to output differential of approximately two volts minimum. ...

... For use with open collector logic outputs, a 50K resistor from this pin supply, such as Pin 5, is required. The SG29055/55A also has an internal pulldown resistor on pin 2 to ground. This resistor, approximately 90K in value, ensures the high current switched output remains off unless actively pulled high ...
