NCV8605 Datasheet, PDF (1/13 Pages) ON Semiconductor – 500 mA, Low IGND, CMOS LDO Regulator with/without Enable and with Enhanced ESD Protection

NCV8605, NCV8606
500 mA, Low I_GND, 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.
