SCY99192BFCT125T2G is a linear voltage regulator specifically designed primarily for use in portable equipment. It is a two-terminal adjustable regulator with a fixed output voltage range of 3.3V to 40V, making it suitable for a wide variety of portable power applications. This high performance regulator features an adjustable output current limit of up to 125mA, low dropout voltage and low quiescent current.

Application Field:

SCY99192BFCT125T2G is ideal for portable equipment, such as mobile phones, small consumer products and portable medical devices. It is also suitable for handheld radio transceiver equipment, providing accurate voltage regulation and excellent thermal performance. It is especially suitable for the stable voltage operation environment of automotive electronic equipment.

Working Principle:

The working principle of SCY99192BFCT125T2G can be explained by its two main components, the error amplifier and the pass element. The error amplifier is responsible for comparing the output voltage to the reference voltage and adjusting the output voltage accordingly. The pass element is a device that regulates the current and voltage flow between the input and output terminals. It is controlled by the error amplifier, which is responsible for comparing the output voltage to the reference voltage. The output setpoint is adjusted by varying the reference voltage. The pass element then adjusts the voltage and/or current at the output, to ensure that it is always equal to the reference voltage.

The output voltage can be adjusted over the range of 3.3V to 40V by varying the reference voltage. The advantage of the linear regulator is that the output voltage is always in direct proportion to the input voltage which allows the output voltage to be kept very accurate over a wide input voltage range. The linear regulator is also able to deliver constant voltage without forming any ripple when the input line is noisy or disconnected.

The SCY99192BFCT125T2G additionally features a current limit function, allowing it to regulate the output current in order to prevent any damage caused by excessive current. The adjustable current limit is set externally, so users can easily determine the maximum current that can be supplied from the device. The device also features a low dropout voltage, meaning it can supply output voltage very close to the input voltage, thus producing very low losses.

SCY99192BFCT125T2G is a high performance linear voltage regulator that is suitable for a wide variety of portable power applications. It features an adjustable output current limit, low dropout voltage and low quiescent current, making it an ideal choice for portable equipment.
