NCP605: Linear Voltage Regulator, CMOS LDO, Low IGND, with Enhanced ESD Protection

Product Description
The NCP605/NCP606 Low Dropout (LDO) Linear Voltage Regulator provides in excess of 500 mA of output current at fixed voltage options or an adjustable output voltage from 5.0 V down to 1.25 V. These devices are designed for space constrained and portable battery powered applications and offer additional features such as high PSRR, low noise operation, short circuit and thermal protection. The devices are designed to be used with low cost ceramic capacitors and are packaged in the DFN6 3x3.3. NCP605 is designed without enable pin, NCP606 is designed with enable pin.
