Description
The LM1117RS-1.2 is a low power positive-voltage regulator designed to meet 1A output current and comply with 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 LM1117RS-1.2 features very low quiescent current and very low dropout voltage of 1V at a full load and lower as output current decreases. It is available as an adjustable or fixed 1.2V, 1.5V, 1.8V, 2.5V, 2.85V, 3.3V, and 5.0V output voltages. The LM1117RS-1.2 is offered in a 3-pin surface mount package SOT-223, TO-252 & SOT-89. The output capacitor of 10㎌ or larger is needed for output stability of LM1117RS-1.2 as required by most of the other regulator circuits.

The LM1117RS-1.2 has the advantage of low quiescent current and low dropout voltage, making it suitable for use in battery-powered applications. It also has a wide range of output voltage options and internal current and terminal protection. However, it requires an output capacitor of 10㎌ or larger for output stability. Additionally, while it is available in surface mount packages, it may not be suitable for all applications due to its maximum input voltage of 20V.
Advantages- Low quiescent current and low dropout voltage
Disadvantages- Requires an output capacitor for stability
- Maximum input voltage of 20V -
