AMS1117 - 1A Low Dropout Voltage Regulator

General Description

The AMS1117 series of adjustable and fixed voltage regulators are designed to provide up to 1A output current and to operate down to 1.2V input-to-output differential.

The dropout voltage of the device is guaranteed maximum 1.3V, decreasing at lower load currents.

Key Features

  • Three terminal Adjustable or Fixed Voltages: 1.25, 1.5V, 2.5V, 2.85V, 3.3V and 5.0V.
  • 1A maximum output current.
  • 1.2V of typical dropout voltage.
  • 0.2% maximum load regulation.
  • 0.4% maximum line regulation.
  • -40 to +125°C temperature range.
  • Available in SOT223, TO-252 and SO-8 package.
  • RoHS & WEEE compliant.

General Description The AMS1117 series of adjustable and fixed voltage regulators are designed to provide up to 1A output current and to operate down to 1.2V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.3V, decreasing at lower load currents. On-chip trimming adjusts the reference voltage to 1.5%. Current limit is set to minimize the stress under overload conditions on both the regulator and power source circuitry. The AMS1117 devices are pin compatible with other three-terminal SCSI regulators and are offered in the low profile surface mount SOT-223 package, in the 8L SOIC package and in the TO-252 (DPAK) plastic package.
