DESCRIPTION
Regulation of output voltage is maintained for TERMPWR voltages as low as 4.0V. When unloaded, quiescent supply current is a low 2mA, allowing continuous connection to the TERMPWR lines. An ultra low power shutdown mode is also available on the SO-8 version. In shutdown the output is high impedance and supply current drops to 100µA (typ.). Current limits in both sourcing and sinking modes, plus on-chip thermal shutdown make the circuit tolerant of output fault conditions. The SC1118 is available in the 3-lead SOT-223 and 8-lead SO-8 packages. SC1118 FEATURES
