Descriptions
The DIO7758 series is a high-accuracy, low-noise, high-speed, high-PSRR, and low-dropout CMOS Linear regulator with high ripple rejection. The devices offer a new level of cost-effective performance in cellular phones, laptop and notebook computers, and other portable devices.
The DIO7758 has the fold-back maximum output current which depends on the output voltage. So the current limit functions both as short circuit protection and as an output current limiter.
The device is available in the DFN2*2-6 package.
