Key Featrues
Ultralow RMS Noise (0.8µVRMS from 10Hz to 100kHz) - This feature ensures minimal noise interference, making the regulator ideal for sensitive applications like RF power supplies and precision instrumentation, where signal integrity is critical.
Ultrahigh PSRR (76dB at 1MHz) - The high Power Supply Rejection Ratio (PSRR) effectively minimizes noise and ripple from the input supply, enhancing the stability and reliability of the output voltage in noisy environments.
Wide Input Voltage Range (1.8V to 20V) - This broad input range allows the regulator to be used in a variety of applications, from low-voltage portable devices to higher-voltage industrial systems, increasing its versatility.
VIOC Pin for Power Dissipation Control - The VIOC pin enables control of an upstream switching regulator, maintaining a constant voltage across the LDO and significantly reducing power dissipation, which improves efficiency and thermal performance.
Programmable Output Voltage via Single Resistor - This feature simplifies the design process by allowing easy adjustment of the output voltage using a single external resistor, making it adaptable to different application requirements.
