Functional Description
The TLE 4470 is a monolithic integrated voltage regulator with two very low-drop
outputs, a main output Q2 for loads up to 350 mA and a stand by output Q1 providing a
maximum of 180 mA. The device is available in both the P-DSO-14-4 and P-DSO-20-6
packages. It is designed to supply microprocessor systems under the severe conditions
of automotive applications and is therefore equipped with additional protection functions
against over load, short circuit and over temperature. Of course the TLE 4470 can also
be used in other applications where two stabilized voltages are required.
The device operates in the wide temperature range of – 40

C to 150
