Description

The AZ2940 is a low dropout three-terminal regulator with a typical dropout of 280mV at 1A output current. The AZ2940 provides current limit and thermal shutdown. On-chip thermal shutdown provides protection against any combination of high current and ambient temperature that would create excessive junction temperatures. The AZ2940 has 1.2V, 1.8V, 2.5V, 3.3V and 5.0V versions.

Feature(s)

· Minimum Guaranteed Output Current: 1A · Dropout Voltage at IOUT=1A: 280mV Typ. (Except 1.2V and 1.8V Versions) · Output Accuracy: ± 1% · Low Ground Current · Internal Current Limit and Thermal Protection · Reversed-battery and Reversed-lead Insertion Protection · Fast Transient Response

Application(s)

  • Cordless Phone
  • Cellular Phone
  • Bluetooth Earphone
  • Digital Camera
  • Portable Electronics
  • WLAN
  • MP3 Player
