The XC6501A251GR-G is a single-channel high-accuracy, low-power linear voltage regulator IC. It can provide up to 250mA output current and 250mV dropout voltage. It is designed to offer high accuracy to satisfy a wide variety of consumer and industrial applications. This high accuracy is achieved through the use of high-quality external resistors and capacitors. The XC6501A251GR-G also offers low noise, low quiescent current, and a maximum operating temperature of 105°C.

The XC6501A251GR-G can operate across a wide output voltage range of 0.7 to 9.0V. It includes several protection features and an enable function, allowing the device to be quickly and easily enabled/disabled. It has a five-pin SOT-23 packaging, making it well suited for compact, space-limited designs. The device is RoHS- and halogen-free, and the maximum junction temperature is rated up to 125°C.

The XC6501A251GR-G’s working principle involves the process of converting an input voltage to a regulated output voltage. The internal circuit of the device contains a power transistor, compared to a typical adjustable voltage regulator, where a control circuit is used to effectively adjust the output voltage. The XC6501A251GR-G uses a feedback loop in order to accurately adjust the output voltage, which consists of a voltage reference, error amplifier, and a voltage divider. The voltage reference unit produces a fixed voltage, usually in the range of 1.25V. This voltage is then applied to the input of the error amplifier. The output of the divider is then applied to the error amplifier. The output of the error amplifier is then used to adjust the output voltage.

The error amplifier compares the actual output voltage to the reference voltage, and then produces an output signal to adjust the output voltage. This output signal drives the power transistor, increasing or decreasing the amount of current flowing through the circuit. This helps to maintain the regulated output voltage. The XC6501A251GR-G also contains an enable pin, which allows for the device to be quickly and easily enabled/disabled.

In summary, the XC6501A251GR-G is part of Torex Semiconductor’s XC6000 series of low-noise, high-precision linear voltage regulators. It is a high-accuracy, low-power linear voltage regulator IC with a wide range of applications. Its working principle involves the use of a feedback loop in which the output voltage is accurately adjusted. It also contains several protection features and an enable pin to allow the device to be quickly and easily enabled/disabled. The XC6501A251GR-G is a valuable solution for consumer and industrial applications, such as LED lighting, industrial automation, biomedical, and home entertainment.
