The XTR70020 highlights performance in terms of dropout voltage (power losses), output voltage stability (over input voltage, load current and temperature), wide range of input voltages (3V to 32V), quiescent current and output current capability (>2A). It provides several preset standard output voltages (0.6V to 15V) and the possibility to obtain other output voltages by using two external resistors. Other features include over current  / short circuit protection, user selectable thermal shut-down, soft start-up / shut-down and automatic transition to low quiescent current mode depending on dropout voltage.

The device can supply sensors and actuators as well as post regulation or primary power supply. As with all other X-REL Semiconductor products, the XTR70020 is able to reliably operate from -60°C to well above +230°C, with expected lifetime of about 5 years at +230°C. Being operational at high temperatures is mandatory in applications where the environment is at elevated temperature or where a power device makes the temperature increase inside the application casing. All X-REL Semiconductor products can be used in applications running at lower temperatures (e.g. from 100°C to 200°C) where extended lifetime is expected or where failing is not an option. For example, the expected lifetime of X-REL Semiconductor parts in an application operating at Tj=150°C is over 35 years.
