The LT6657 operates across a temperature range from –40 to 125°C and was designed for demanding high performance instrumentation, test equipment and automotive systems.The LT6657 can operate on a supply voltage from 50mV above the output voltage, up to 40V, and features a supply current of 1.2mA. In shutdown mode, power consumption is 4µA. Load regulation error is less than 6ppm/mA and line regulation error is less than 4ppm/V.
This part is said to be safe under reverse battery conditions, and includes current protection when the output is short-circuited and thermal shutdown for overload conditions. A shutdown is included to allow power reduction while enabling a quick turn-on.
The LT6657 is available in an 8-lead MSOP package and is currently in production with a 2.5V output version. Additional voltage options are in development.
