Product Preview

1.0 A Positive Voltage

Regulators

The NCP7800E series consists of 3 pin, fixed output, positive linear

voltage regulators, suitable for a wide variety of applications. These

regulators are extremely rugged, incorporating internal current

limiting, thermal shutdown and safe-area compensation. With

adequate heat sinking they can deliver output currents in excess of

1.0 A. Designed as direct replacements for the popular MC7800

family, these products offer enhanced ESD protection.

Figure 1. Application Schematic

A common ground is required between the input and

the output voltages. The input voltage must remain

typically 2.0 V above the output voltage even during the

low point on the input ripple voltage.
