Bare Die Data Sheet: SiS5219A

SiS4219A suits start-up conditions with high inrush current demand up to 1A. Output is set by x2 external resistors & enabled or shut down by CMOS/TTL signals. Low dropout voltage, low ground current & ultra-low noise parameters enable performance.
This bare die is an upgrade of the Micrel / Microchip MIC5219 featuring wider voltage range, higher output current, lower voltage dropout & lower ground current. On-chip enable / shutdown & rugged protection features further enhance this device.
  • Wide VIN 2.4V - 16V
  • Low dropout voltage:
    • <330mV (IOUT = 500mA)
    • <550mV (IOUT = 1A)
  • 0.003% Line, 0.2% Load regulation (Typ)
  • Low ground current: <13mA (IOUT = 500mA)
  • Low standard output noise: 500nv/√Hz
  • Ultra-Low output noise option: 300nv/√Hz with CBYPASS
  • CMOS/TTL-Compatible Enable/Shutdown Control
  • Near-Zero Shutdown Current
  • Current + thermal limiting + rev. polarity protection
  • Low temperature coefficient
