XC6501A28AGR-G is a member of Richtek Technology Corporation\'s High PSRR Low Noise Linear Regulator Family, specifically designed to meet the requirements of light load low PSRR designs. This voltage regulator is designed to cater to exacting applications, such as Analog, Digital, Power management and Motor Control, for stable output and minimal noise.

It regulates an output voltage as low as 0.85V with maximum load current of 1mA. It supports a wide input voltage range between 2.6V and 5.5V. The device is available in an SOIC-8 package and is also RoHS compliant, being lead free with halogen free option.

The XC6501A28AGR-G operates in a fixed voltage mode, employing a feedback network to control the output voltage. It operates in two output stages: an ultra low dropout voltage pass element in the forward direction and an enhancement MOSFET in the reverse direction, which acts as a reverse current blocker. This ensures that a finite voltage drop is maintained in the pass element for regulation and prevents reverse currents from flowing through it.

The XC6501A28AGR-G is based on a CMOS process which ensures high performance and stability in terms of output accuracy and low noise. Its low quiescent current of 1.2mA (typical) is ideal for applications requiring minimal power dissipation. The device has an available load regulation feature which enables the user to adjust the output voltage to respond to varying load conditions.

The XC6501A28AGR-G provides two protection features – a thermal protection feature to protect the device from high temperature conditions and a reverse current protection feature to prevent reverse current flow. The device features an enable pin to turn off the output in order to save power when the device is not in use.

The XC6501A28AGR-G has excellent PSRR performance, low output noise and fast transient response which makes it ideal for a wide range of battery powered applications. It is a versatile device which can be used for supply voltage regulation of digital and analog circuits, motor control and power management in wireless, embedded and portable systems.
