Mintech Interconnect and Test has introduced a low dropout voltage regulator with adjustable current, remote sense capability and a low on resistance of typically 0.25ohm. The MBT1185 is a hermetically sealed device, available in an industry standard 10-lead ceramic flatpack, and is targeted at high reliability and space applications. The body of the package measures 6.4 x 6.4mm.
The output voltage range is 2.5 to 25V with 1% accuracy on the internal reference voltage.
The regulator output is guaranteed to shutdown when the program current is less than 1uA, allowing external logic control of output voltages.
Setting an accurate external current limit is achieved with a single resistor.
The value of this resistor is determined by dividing 15kohm by the desired current limit.
Therefore a 2A current limit is achieved by using a 7.5kohm resistor.
A second fixed internal current limit prevents damage to the device in the event that the programming current accidentally exceeds the maximum.
The MBT1185 is available at commercial, industrial and military temperature grades and is suitable for a range of industrial, military and space applications.
An option screened in accordance with MIL-STD-883C is also available.
These devices are manufactured and tested at Mintech's ISO9001:2000 approved UK factory.
Mintech is committed to long-term support of high-reliability ceramic and plastic components and continues to expand its range, covering many technologies.
