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 °C.

The stand by regulator transforms an input voltage V_Iin the range of 5.6 V ≤ V_I≤ 45 V to

V_Q1rated= 5 V within an accuracy of 2%, whereas the main regulator is adjustable. By use

of an external voltage divider the main output voltage can be set to V_Q2≥ 5 V for the

Semiconductor Group
