XTR70020 is a family of high-temperature, high-input voltage, 2Amp ultra low dropout voltage regulators designed for extreme reliability high voltage and high temperature applications. Being able to operate with input voltages from 3.0V to 30V, XTR70020 parts can source a current of 2A at +230°C while providing excellent regulation characteristics with a dropout as low as 1.2V. Several preset reference voltages are available from 0.6V to 15V allowing output voltages from 0.6V to virtually 30V. Four protection features are implemented to ensure a good operation and reliability of the circuit: UVLO, hiccup modes short-circuit protection, customer selectable thermal shutdown, soft turn-on/off. XTR70020 parts can be used in a wide range of applications such as high fan-out and low-dropout regulators, adjustable power supply, current sources, as well as precision bridge excitation. Special design techniques were used allowing XTR70020 parts to offer a precise, robust and reliable operation in critical applications. Full functionality is guaranteed from -60°C to +230°C, though operation well below and above this temperature range is achieved. XTR70020 parts have been designed to reduce system cost and ease adoption by reducing the learning curve and providing smart and easy to use features. Parts from the XTR70020 family are available in ruggedized SMT and thru-hole packages, as well as bare dies.
