NCP7812TG Datasheet, PDF (1/12 Pages) ON Semiconductor – 1.0 A Positive Voltage Regulators

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

Output
C_O**
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.
* C_in is required if regulator is located an appreciable
distance from power supply filter.
** C_O is not needed for stability; however,
it does improve transient response. Values of less
than 0.1 mF could cause instability.
