500 mA, Low IGND, CMOS LDO Regulator with/without Enable and with Enhanced ESD Protection

ON Semiconductor 

NCV8605, NCV8606

500 mA, Low IGND, CMOS

LDO Regulator with/without

Enable and with Enhanced

ESD Protection

The NCV8605/NCV8606 provide 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. NCV8605 is designed

without enable pin, NCV8606 is designed with enable pin.
