The LM1117S-1.2 is a Low Dropout Regulator (LDO) Positive Fixed 1.3V @ 1A 12V 1.2V 1A SOT-223 RoHS manufactured by HTC Korea. This component is used to reduce the supply voltage on devices operating on a 12V input. It is designed to maintain proper device operation at a lower voltage, even when there is a higher input voltage. This part is also RoHS compliant, meaning it has no lead in its construction. With a maximum input voltage of 12V, the LM1117S-1.2 can provide a regulated output voltage of up to 1.3V. It can handle up to 1A of current in its SOT-223 package and has a fast transient response time. This part is ideal for small form factor devices, such as those in medical equipment, consumer electronics, and automotive systems.
