DD - Industrial, SC-70 (E): -40C to +85C Both devices are available in 3-Pin SC-70 and SOT-23B - Extended, SOT-23, SC-70 (V): -40C to +125C packages. The TCM809/TCM810 is optimized to reject fast Applications transient glitches on the V line. A low supply current DD Computers of 9 A (typ., V = 3.3V) make these devices suitable DD for battery-powered applications.
