PRODUCT DESCRIPTION

XTR70010 is a family of low-power voltage regulators/references designed for extreme reliability and high temperature applications. Being able to operate with input voltages from 2.8V to 5.5V, XTR70010 parts can source a current of 1.5A at +230°C while providing excellent regulation characteristics with a dropout as low as 1.9V. Moreover, it can supply a large range of output voltages from 0.5V to 3.6V thanks to an accurate current mode bandgap reference. Six protection systems are implemented to ensure a good operation and reliability of the circuit: UVLO, Short-circuit hiccup mode, thermal shutdown, fast output overshoot killer, soft turn-off and power supply supervision in case of bad input decoupling. XTR70010 parts can be used on a wide range of applications such as high fan-out and low dropout regulators/references, adjustable power supply, current sources, as well as precision bridge excitation. Special design techniques were used allowing XTR70010 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. XTR70010 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 XTR70010 family are available in ruggedized SMT and thru-hole packages. Parts are also available as bare dies.
