For product comparison, please consider:

The MCP1703 is a CMOS, low dropout voltage regulator with 250 mA maximum output current. MCP1703 works with input voltage of up to 16V and in combination with its low current consumption of 2 µA is an ideal solution for applications using multi-cell, 9V alkaline or one-, two- or three- cell lithium-ion batteries. It is available in space efficient SOT23A and SOT89 packages or in a thermally capable 3-pin SOT223.

For new designs, please consider the MCP1703A, which contains several improvements over the MCP1703.

  Low 2.0 µA quiescent current (typical)

  Wide input operating voltage range: 2.7V to 16.0V

  High output current capability:

  250 mA for output voltages ≥ 2.5V

  200 mA for output voltages < 2.5V

  Output voltage range 1.2V to 5.5V in 0.1V increments (50 mV increments available upon request)

  Stable with 1.0 µF to 22 µF ceramic, tantalum, or aluminum output capacitors

  Short-circuit protection

  Overtemperature protection

  Package Options: 3-Pin SOT-23A, 3-Pin SOT-89,TO-92-3
