LP2981-N Datasheet 100-ma Ultra-low Dropout Regulators

Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community LP2981-N SNOS773N – MARCH 2000 – REVISED APRIL 2016 LP2981-N Micropower 100-mA Ultralow Dropout Regulator in SOT-23 Package.

General Description

The LP2981-N is a 100-mA, fixed-output voltage regulator designed specifically to meet the requirements of battery-powered applications.

Using an optimized Vertically Integrated PNP (VIP) process, the LP2981-N delivers unequaled performance in all specifications critical to batterypowered designs: Dropout Voltage: Typically 200 mV at 100-mA load, and 7 mV at 1-mA load.

Ground Pin Current: Typically 600 μA at 100-mA load, and 80 μA at 1-mA load.

Key Features

  • 1 Operating Input Voltage Range: 2.1 V to 16 V.
  • Ultralow-Dropout Voltage.
  • Output Voltage Accuracy 0.75% (A Grade).
  • Specified 100-mA Output Current.
