Semtech SC563

Dual Output 300mA LDO Linear Regulator

Add to Watch List

The SC563 is a dual output, low dropout linear voltage regulator designed for use in battery powered applications and other applications with space constraints and low power requirements. The SC563 provides fixed output voltages up to 300mA of load current per channel. Fixed output voltages for each output eliminates the need for external feedback resistors.


  • Input voltage range — 2.3V to 5.5V
  • Two 300mA (maximum) outputs
  • Dropout at 300mA load — 180mV (Typ)
  • Quiescent supply current — 50μA (x2)
  • Shutdown current — 100nA
  • Output noise — 100μVRMS/V
  • Over-temperature protection
  • Short-circuit protection
  • Under-voltage lockout
  • Internal output discharge 100ohm
  • MLPD-UT8, 1.6mm x 1.2mm x 0.6mm package
