Description

The AZ2117 has been optimized for low voltage where transient response and minimum input voltage are critical. It provides current limit and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within ±1%. On-chip thermal shutdown provides protection against a combination of high current and ambient temperature that would create excessive junction temperature.

The AZ2117 is available in ADJ output voltage version. It is available in an adjustable version which can set the output voltage with two external resistors.

Feature(s)

  • Current Limit: 1.35A (Typ)
  • Output Noise from 10Hz to 10KHz: 0.003% of VOUT
  • PSRR at IOUT = 300mA and f = 120Hz: 60dB
  • Output Voltage Accuracy: ±1% (Except 1.2V Version)
  • On-chip Thermal Shutdown
  • Maximum Quiescent Current: IQMAX = 1mA
  • Compatible with Low ESR Ceramic Capacitor
  • Operation Junction Temperature: -40°C to +125°C

Application(s)

  • USB Device
  • Add-on Card
  • DVD Player
  • PC Motherboard
