(VI > 4.5V, TA ≤ 70°C) - - - - - - 68% typ. efficiency at 6V Very low quiescent current: 1.2m A in on mode, 10µA in shut down mode Soft start Very low noise output 160KHz fixed frequency oscillator Mixed bipolar-CMOS technology SO-8 and TA = 0°C to 70°C) and 275m A (typical value at TA = 25°C, VO = -5V). A logic controlled shut down pin that interfaces directly with microprocessor reduces supply current to only 10m A. Input to Output differential voltage is limited to VI+|VO|<12.7V. No load supply current is 1.2m A Description The ST755 is an adjustable inverting switch-mode DC-DC regulator with internal Power MOSFET that generators an adjustable negative output from a voltage input of 2.7V to 11V, output current guaranteed at 200m A (for VI > 4.5V, VO = -5V Table 1.
