MC7800
Series
Three-Terminal Positive
Voltage Regulators
These voltage regulators are monolithic integrated circuits designed as
fixed–voltage regulators for a wide variety of applications including local,
on–card regulation. These regulators employ internal current limiting,
thermal shutdown, and safe–area compensation. With adequate heatsinking
they can deliver output currents in excess of 1.0 A. Although designed
primarily as a fixed voltage regulator, these devices can be used with
external components to obtain adjustable voltages and currents.
• 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 2% and 4% Tolerance
• Available in Surface Mount D2PAK and Standard 3–Lead Transistor

XX indicates nominal voltage.
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 µF could cause instability.

NOTES:
1. Tlow = 0°C for MC78XXAC, C Thigh = +125°C for MC78XXAC, C, B
= – 40°C for MC78XXB
2. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account
separately. Pulse testing with low duty cycle is used.
