700ma Smartldo - Semtech Corporation

The SC1537 is designed to maintain a glitch-free 3.3V output when at least one of two inputs, 5V (VIN) and 3.3V (VAUX), is present. Whenever VIN exceeds a predetermined threshold value, the internal 3.3V linear Regulator is enabled, and DR is pulled high. When VIN falls below a lower threshold value, DR is pulled low and the internal linear Regulator is turned off. DR has been designed to drive the Gate of an external low threshold P-Channel MOSFET which CAN be used to connect the 3.3V supply directly to the Regulator output. This ensures an uninterrupted 3.3V output even if VIN falls out of specification. A maximum RDS(ON) of 100m is recommended. By Semtech Corporation
