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 VI in the range of 5.6 V VI 45 V to VQ1rated = 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 VQ2 5 V for the Semiconductor Group
