Dual Low-Drop Voltage Regulator TLE 4470 Features - Stand-by output 180 m A; 5 V ± 2% - Adjustable reset switching threshold - Main output 350 m A; tracked to the stand-by output - Low quiescent current consumption in standby mode - Disable function for main output - Wide operation range: up to 45 V - Very low dropout - Power-On-Reset circuit sensing the stand-by voltage - Early warning parator for supply undervoltage - Output protected against short circuit - Wide temperature range: -40 °C to 150 °C - Overtemperature protection - Overload protection - Green Product (Ro HS pliant) - AEC Qualified Functional Description P-DSO-14-1, -4, -7 PG-DSO-14 P/PG-DSO-20-1,-6,-7,-9,-14,-1 PG-DSO-20 The TLE 4470 is a monolithic integrated voltage regulator with two very low-drop outputs, a main output Q2 for loads up to 350 m A and a stand by output Q1 providing a maximum of 180 m A. The device is available in two packages the PG-DSO-14 and PG-DSO-20. It is designed to supply microprocessor systems under the severe conditions of automotive applications and is therefore equipped with additional protection functions against overload, short circuit and overtemperature. Of course the TLE 4470 can also be used in other applications where two stabilized voltages are required. The device operates in the wide junction 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 VQ1,nom = 5 V within an accuracy of 2%, whereas the main regulator is adjustable.
