The LP2983 is a 150-mA, fixed-output voltage regulator designed to provide tight voltage regulation in applications with output voltages ≤ 1.2 V.

Using an optimized vertically integrated PNP (VIP) process, the LP2983 delivers unequaled performance in all critical specifications:

  • Ground pin current: Typically 825 µA at a 150-mA load, and 75 µA at a 1-mA load.
  • Enhanced stability: The LP2983 is stable with output capacitor ESR down to zero, which allows the use of ceramic capacitors on the output.
  • Precision output: 1% tolerance output voltages available (A grade).
  • Smallest possible size: SOT-23 package uses absolute minimum board space.
For all available packages, see the orderable addendum at the end of the data sheet.

  • Operating Input Supply Voltage: 2.2 V to 16 V
  • Output Current: 150 mA
  • Low ZOUT: 0.3 Ω Typical (10 Hz to 1 MHz)
  • Stable with Low-ESR Output Capacitor
  • Low Ground Pin Current at All Loads
  • Output Voltage Accuracy 1% (A Grade)
  • High Peak Current Capability
  • Wide Supply Voltage Range (16 V Maximum)
  • Overtemperature and Overcurrent Protection
  • −40°C to +125°C Junction Temperature Range
  • Requires Minimum External Components
