... SCSI-II specifications with a fixed output voltage of 2.85V. This device is an excellent choice for use in battery-powered applications, as active terminators for the SCSI bus, and portable computers. The AS1117 features very low quiescent current and very low dropout voltage of 1. full load and lower as output current decreases. AS1117 is available as an adjustable or fixed 2.85V, 3V, 3.3V, and 5V output voltages. ...

... APPLICATION NOTES EXTERNAL CAPACITOR To ensure the stability of the AS1117 an output capacitor of at least 10 F (tantalum) (aluminum) is required. The value may change based on the application requirements on the output load or temperature range. The capacitor equivalent series resistance (ESR) will effect the AS1117 stability. The value of ESR can vary from the type of capacitor used in the applications ...
