Automotive and industrial linear voltage regulators operate to 175C

A new fixed-voltage 5V linear voltage regulator ruggedized for high-reliability and high-temperature automotive and industrial applications, the CMT-ANTARES Series has been introduced by Cissoid. The devices deliver up to 200mA to the output load from input voltages between 5.5V and 30V. The output voltage is stabilized to 5V +/-5% including all possible variations: initial accuracy, temperature changes from -55C up to 175C (Tj), line and load regulations. The harsh-environment CMT-ANTARES Series not only operates reliably at high temperatures but it is robust against severe electrical anomalies. The chip is immune to latch-up, resists to ESD events up to 6KV (HBM), is protected against short circuits and power overloading, by a current limiter and an over temperature protection (OTP) triggering above 225C (Tj). Moreover, the CMT-ANTARES offers comfortable safety margins with maximum absolute ratings for temperature and input voltage extending respectively to 200C (Tj) and 40V. The device is housed in a 3-pin TO-263 plastic package. The junction-to-case thermal resistance is only 4.6C/W. The combination of high operating junction temperature and a low junction-to-case thermal resistance allows minimising the cooling requirements, e.g. by using a smaller copper thermal pad on the PCB. The 3-pins package makes it easy to integrate CMT-ANTARES on the PCB and allows a drop-in replacement of commercial voltage references, says the company.
