S-1155B40-U5T1U is a linear voltage regulator that provides a regulated output voltage for a variety of applications. It is designed to be used in power management ICs (PMICs) for systems where power supply noise and ripple must be minimized.
This regulator is based on a standard three-terminal configuration consisting of an output, ground, and input voltage pins. The output voltage can be easily adjusted by changing the voltage applied to the input voltage pin.
The S-1155B40-U5T1U operates in a constant-voltage mode and requires a minimum load of 8mA in order to maintain its rated output voltage. In the event of an overload, the regulator is designed to safely shut down the output current to protect it from damage.
In addition, the S-1155B40-U5T1U features a built-in thermal shutdown circuit which prevents the regulator from being damaged due to excessive temperatures. It is also designed to provide protection against over-voltage, reverse polarity, and reverse current.
The S-1155B40-U5T1U is ideal for a variety of applications including, but not limited to, batteries, logic and memory circuits, and DC-DC converters. It is capable of supplying up to 40mA of current, making it suitable for low-power systems.
The working principle of the S-1155B40-U5T1U is relatively simple. The inputs to the regulator are the output voltage, ground, and input voltage. The output voltage is set by the input voltage and is adjusted via an external resistor.
When the output voltage reaches the desired value, the regulator adjusts the amount of current provided by the input voltage to maintain the output voltage. In the event of an overload or over-voltage situation, the regulator shuts down the output current to protect it from damage.
The S-1155B40-U5T1U is a simple and efficient voltage regulator for power management applications. It is designed to provide a reliable and stable voltage supply, even in the event of overloads or over-voltage conditions.
