The S-1137B30-I6T2U Voltage Regulator is a linear, 3-terminal, adjustable, positive voltage regulator with a wide operating current range of 3.0A. It is designed to operate with a wide input voltage range up to 44V and a regulated output voltage range of 0.8V to 27V. The adjustable output voltage can be easily set using two external resistors or a single pot or trim pot connected to an external voltage source.

The S-1137B30-I6T2U covers a wide range of applications such as regulating the output voltage for microcontrollers, analog-to-digital converters and digital-to-analog converters. It can also be used for backlighting, linear regulators, power supplies, DC to DC converters, switching regulators and other voltage regulation applications. It operates with a maximum input voltage of 44V and a maximum current of 3.0A. It supports a wide operating temperature range of -40°C to +85°C.

The S-1137B30-I6T2U Voltage Regulator has an internal over current protection (OCP) that limits the output current to 3.0A. In order to protect the IC from output shorts and other fault conditions, the over-voltage protection (OVP) circuit limits the output voltage to 30V. For more protection, the built-in over-temperature protection (OTP) shuts down the IC when the die temperature rises above 150°C. The IC also has an input under-voltage lockout function that ensures that the output voltage remains at 0V when the input voltage drops too low.

When it comes to the working principle of the S-1137B30-I6T2U Voltage Regulator, it follows the same basic operation as other linear regulators. A differential amplifier circuit is used to compare the output voltage with the output reference voltage extracted from the feedback resistors. If the output voltage falls below the reference voltage, the error amplifier will emit a larger drive current to the output transistor, causing the output transistor to increase its conduction, thus increasing the output voltage. Conversely, if the output voltage exceeds the reference voltage, the error amplifier will reduce its drive current to the output transistor, causing the output transistor to decrease its conduction, thus lowering the output voltage. This process is repeated continuously to maintain the output voltage at a steady level.

The S-1137B30-I6T2U Voltage Regulator is a highly reliable and robust linear regulator, with features such as current limiter, over-voltage protection and over-temperature protection. It offers a wide range of operating current and voltage, making it suitable for a variety of applications. It is an ideal solution for regulating output voltage for microcontrollers, DC to DC converters and switching regulators, as well as other voltage regulation applications.
