S-1135A24-U5T1G Application Field and Working Principle

The S-1135A24-U5T1G is a linear voltage regulator that belongs to the PMIC (Power Management IC) family of products. It is designed to regulate the output voltage of a power source, providing a constant output voltage across a wide range of input voltages and temperatures.

The S-1135A24-U5T1G is typically used in systems that require a low power supply and a reliable, cost-effective voltage regulator. Such applications include automotive, communications, industrial, and computer systems. The S-1135A24-U5T1G is well suited to modern power-management designs, due to its ability to provide low noise and efficient transient response for low power regulation.

The S-1135A24-U5T1G regulator has an output voltage range of 1.2V to 24V. It can deliver up to 2.2A of continuous current and is rated up to a maximum output voltage of 28V. The S-1135A24-U5T1G features an adjustable voltage regulator, in which a single external resistor can set the desired output voltage. The device can also be programmed by applying a voltage to the VTRIM pin to adjust the output voltage level. The regulator is also equipped with over-voltage protection.

The S-1135A24-U5T1G operates from a single voltage input rail, making it suitable for use in applications where space is at a premium. It employs an internal self-biasing circuit to provide current limit and short-circuit protection. The device can also be switched off with a logic-level signal.

The basic circuitry of the S-1135A24-U5T1G is made up of an integrated pass element, which is designed to limit the source voltage output. The voltage reference is provided by an internal voltage regulator, which is connected to an adjustable voltage divider. This voltage reference is connected to the gate of the pass element, which allows it to regulate the output voltage. The output voltage can be adjusted by a voltage applied to the VTRIM pin.

In addition to its low-power regulation capability, the S-1135A24-U5T1G also offers over-current and over-temperature protection. An internal current-sense amplifier can detect output current levels, and provide a warning signal if the output current exceeds the specified limit. Over-temperature protection is provided by a thermal shut-down circuit, which monitors the temperature of the device and reduces the output current if the temperature exceeds a pre-set level.

The S-1135A24-U5T1G is a versatile and cost-effective linear voltage regulator for applications that require high accuracy, low noise, and good transient response. The wide input voltage range, low power loss, and low noise performance make it ideal for use in a wide range of applications.
