1.0 A Positive Voltage Regulators

ON Semiconductor 

NCP7800

1.0 A Positive Voltage

Regulators

The NCP7800 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.

Features

• Output Current in Excess of 1.0 A

• No External Components Required

• Internal Thermal Overload Protection

• Internal Short Circuit Current Limiting

• Output Transistor Safe−Area Compensation

• Output Voltage Offered in 4% Tolerance

• Available in Standard 3−Lead Transistor Packages

• For Tighter Tolerances and Extended Operating Range Refer to MC7800

• Enhanced ESD Tolerance: HBM 4 kV (5 V and 8 V Options), 3 kV

(12 V and 15 V Options), and MM 400 V

• These are Pb−Free Devices

Input

Cin*

0.33 mF

NCP78XX

Output

CO**

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.

XX These two digits of the type number indicate

nominal voltage.

* Cin is required if regulator is located an appreciable

distance from power supply filter.

** CO is not needed for stability; however,

it does improve transient response. Values of less

than 0.1 mF could cause instability.
