Typical Application for LD39015 150 mA low quiescent current and low noise voltage regulator

Typical Application for the STP04CM05 is a high-power LED driver and 4-bit shift register designed for Power-LED applications. The STP04CM05 contains a 4-bit serial IN, parallel OUT shift register that feeds a 4-bit Dtype storage register. In the output stage, four regulated current sources were designed to provide 80-400 mA constant current to drive high power LEDs
