LDO-Voltage-Regulator-Series S-1137 with Soft-Start (English 2009)

| Press

Prominent property of this new Series of CMOS voltage regulator is a Soft-Start function settable by one external capacitor. This will eliminate dangerous inrush current of approximately 400mA and reduce it to uncritical 20mA. The High-Ripple-Rejection-Ratio of 70dB typ. at 1KHz and VOUT= 1,0V
is further insuring that noticeable input voltage transients, as they occur with the fluctuation of neighbouring loads, will be suppressed.
