DESCRIPTION

The TL720M devices are monolithic integrated low-dropout voltage regulators offered in 3-pin TO packages. An

and are short-circuit proof. At overtemperature, the TL720M devices are turned off by the incorporated

temperature protection.

The control amplifier compares a reference voltage to a voltage that is proportional to the output voltage and

drives the base of the series transistor via a buffer. Saturation control as a function of the load current prevents

any oversaturation of the power element. The device also incorporates a number of internal circuits for protection

against:

•

Overload

•

Overtemperature

•

Reverse polarity
