S-1112B51MC-L7KTFU

The S-1112B51MC-L7KTFU, which belongs to PMIC (Power Management ICs) - Voltage Regulators - Linear, is a powerful low noise voltage regulator. It can provide several different linear outputs over a wide input voltage range. As a low noise regulator, it provides stability, noise control and flexibility over its lifetime under normal operating conditions. It also provide transient response in response to output load or input voltage changes.It has a high level of protection including over-temperature, over-current protection, reversed supply protection, reverse voltage protection and voltage overload protection. The S-1112B51MC-L7KTFU also includes smooth start feature which increases the output voltage slowly to minimize any potential surge and noises.The S-1112B51MC-L7KTFU is typically used to regulate the voltage of a low voltage power supply, such as a laptop or server power supply. In addition, it can also be used for power conditioning applications, such as for point of load (POL) supplies. Basically, the S-1112B51MC-L7KTFU is a low noise five outputs regulator. It has a wide input voltage range from 2.2V to 5.5V, which can be adjustable down to 0.91V. The output ranges from 0.9V to 4.15V, adjustable down to 0.6V. The linear regulator has a quiescent current of 6mA and operating current of over 1.2mA at full load, with a line and load regulation of 0.2% and 0.5% respectively. It also has a very low noise output, with noise voltage of 7uVrms and a ripple current of 0.2uA. With its low ESR (equivalent series resistance), it can deliver higher output current under normal operation.The S-1112B51MC-L7KTFU application field and working principle is simple yet powerful. The device includes a voltage reference and a pass transistor within its package. The reference input determine the output voltage, while the pass transistor (controlled by the voltage reference) adjusts the voltage level to the desired output voltage.The output of the S-1112B51MC-L7KTFU is determined by a combination of the output control terminal and the external feedback network. The feedback network compares the output voltage of the S-1112B51MC-L7KTFU with the desired output voltage. If the voltage is too high, the output control terminal will open the pass transistor, consequently reducing the output voltage. Similarly, when the voltage is too low, the output control terminal will close the pass transistor, thereby increasing the output voltage.In summary, the S-1112B51MC-L7KTFU is a powerful and reliable low noise voltage regulator which can provide various adjustable output voltage in a wide input voltage range. It has a high level of protection and can provide fast and stable response to both output load and input changes. Moreover, it has low noise output, low quiescent and operating current, and low ESR for higher output current delivery. With the combination of these features, the S-1112B51MC-L7KTFU can be used in a wide range of applications from power supply regulation to power conditioning.
