Several features make the LT1175 very user-friendly. The SHDN pin can interface directly to either positive or negative logic levels. Unlike prior regulators, the increase in quiescent current during a dropout condition is actively limited. The LT1175 offers complete protection including user-selectable current limit at 200mA, 400mA, 600mA and 800mA, power limiting (current limit foldback), thermal shutdown and the ability to force the output to reverse voltage without damage or latchup.
In addition to the SOIC-8 and power DD-Pak packages, the LT1175 is available in a 3-lead SOT-223, a through-hole power TO-220 package and an 8-pin PDIP package. C-grade operating junction temperature is 0°C to +125°C, I grade is specified from -40°C to +125°C, and MP grade is -55°C to +125°C. 1k
