NCP605 Datasheet, PDF (1/13 Pages) ON Semiconductor – 500mA, Low IGND, CMOS LDO Regulator with/without Enable and with Enhanced ESD Protection

NCP605, NCP606
500mA, Low I_GND, CMOS
LDO Regulator with/without
Enable and with Enhanced
ESD Protection
The NCP605/NCP606 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.
NCP605 is designed without enable pin, NCP606 is designed with
enable pin.
