XC6902NA51PR-G

The XC6902NA51PR-G Voltage Regulator is a linear power management integrated circuit (PMIC) designed for use in microelectronic circuitry. The purpose of the XC6902NA51PR-G is to provide accurate and reliable output voltage regulation for various applications.The XC6902NA51PR-G features a built-in 1.2V to 6.0V adjustable output voltage regulator that is optimized for low noise operation. It also features an on-chip LDO with an adjustable output voltage and current limitation. The LDO regulates the output voltage to within a wide range of 5-50V and delivers currents up to 1A. In addition, the XC6902NA51PR-G includes a total of 8 pins, a low-dropout (LDO) mode, internal under-voltage lockout, and an integrated output stage.The XC6902NA51PR-G is suitable for a wide range of applications and applications that require reliable and efficient voltage regulation, such as consumer electronics, automotive, industrial and medical devices. It is especially well-suited for consumer and industrial LED lighting, LED driver applications, and power supply designs.The XC6902NA51PR-G’s regulator is based on a Bipolar Junction Transistor (BJT) topology and provides high-efficiency, low-noise and low-temperature operation. This voltage regulator is designed to provide superior output noise, fast transient response and temperature stability, which is important for reliable operation.The XC6902NA51PR-G has an adjustable output voltage range of 1.2V to 6.0V. The regulator is capable of providing up to 1A of continuous output current at the nominal output voltage with a maximum of 25 VDC. An adjustable low-dropout (LDO) mode and under-voltage lockout features are also included, allowing it to operate as a current-limited voltage regulator if the input voltage is lower than the output voltage.The XC6902NA51PR-G consists of an error amplifier, oscillator and driver connected in series. The error amplifier senses errors between the output voltage and an internal reference voltage and produces a signal to correct the output voltage. The oscillator and driver then produce the output voltage from the input voltage. The output voltage is then compared with the preset current limit value, which is set via an internal digital-to-analog converter (DAC). If the output voltage reaches the DAC current limit threshold, the output current is limited and the error amplifier turns the oscillator and driver off until the input voltage is again raised above the DAC current limit value.The XC6902NA51PR-G’s high-efficiency linear regulator architecture allows it to be used in power systems with wide input voltage ranges and a variety of output voltage requirements. Moreover, the on-chip LDO ensures that the output voltage is kept within a safe operating range while the current limit feature keeps the output current under control in the event of a fault.In summary, the XC6902NA51PR-G is an efficient and reliable linear voltage regulator PMIC suitable for a wide range of electronic applications. By integrating a high-efficiency, low-noise LDO, current limit and under-voltage lockout feature, the XC6902NA51PR-G enables safe, efficient and reliable output voltage regulation.
