MCP1703A - Low Quiescent Current LDO Regulator

General Description

The MCP1703A is an improved version of the MCP1703 low dropout (LDO) voltage regulator that can deliver up to 250 mA of current while consuming only 2.0 µA of quiescent current (typical).

Key Features

  • Reduced Ground Current During Dropout.
  • Faster Startup Time.
  • 2.0 µA Typical Quiescent Current.
  • Input Operating Voltage Range: 2.7V to16.0V.
  • 250 mA Output Current for Output Voltages ≥ 2.5V.
  • 200 mA Output Current for Output Voltages < 2.5V.
  • Low Dropout Voltage, 625 mV Typical @ 250 mA for VR = 2.8V.
  • 0.4% Typical Output Voltage Tolerance.
  • Standard Output Voltage Options: - 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 4.
