Product Overview NCP690: Linear Voltage Regulator, CMOS VLDO, 1.0 A For complete documentation, see the data sheet Product Description The NCP690/ NCP691 /NCP692 devices are designed to be Very Low Dropout (LDO) 1 Amp Linear Voltage regulators. This new CMOS VLDO family provides 1A of output current in either fixed voltage options or an adjustable output voltage from 5.0V down to 1.25V. The devices are designed for space constrained and portable battery powered applications and offer many important features such as high PSRR, low Quiescent and Ground current consumption, low noise operation and short circuit and thermal protection. They offer enhanced ESD protection compared to standard CMOS LDOs and are designed to be used with low cost ceramic capacitors. The NCP691 includes an Enable low function, the NCP692 an enable high, and all three products are packaged in the 6Lead DFN3x3 package. Features Benefits • Output Voltage Options: Adjustable, 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5.0 V - Contact Factory for Other Voltage Options • Current Limit Protection • Thermal Shutdown Protection • Typical Noise Voltage of 15 Vrms without a Bypass Capacitor • Available in the most popular voltage options.
