Simplified Application
A common ground is required between the input and
the output voltages. The input voltage must remain
typically 1.7 V above the output voltage even during
the low point on the input ripple voltage.
XX these two digits of the type number indicate
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. If needed, use a

MOTOROLA ANALOG IC DEVICE DATA
This family of fixed voltage regulators are monolithic integrated circuits
capable of driving loads in excess of 1.0 A. These three–terminal regulators
employ internal current limiting, thermal shutdown, and safe–area
compensation. Devices are available with improved specifications, including
a 2% output voltage tolerance, on A–suffix 5.0, 12 and 15 V device types.
Although designed primarily as a fixed voltage regulator, these devices
can be used with external components to obtain adjustable voltages and
currents. This series of devices can be used with a series–pass transistor to
boost output current capability at the nominal output voltage.
Output Current in Excess of 1.0 A
No External Components Required
Output Voltage Offered in 2% and 4% Tolerance*
Internal Thermal Overload Protection
Internal Short Circuit Current Limiting
Output Transistor Safe–Area Compensation
