LR1117A - 1A Adjustable/Fixed Low Dropout Linear Regulator

General Description

The LR1117A and LR1117A-1.8, -2.5, -2.85, -3.3 and -5 are low dropout three-terminal regulators with 1A output current capability.

These devices have been optimized for low voltage where transient response and minimum input voltage are critical.

Key Features

  • Low dropout voltage.
  • Load regulation: 0.05% typical.
  • Trimmed current limit.
  • On-chip thermal limiting.
  • Standard SOT-223, TO-220, and TO-252 packages.
  • Three-terminal adjustable or fixed 1.8V, 2.5V, 2.85V, 3.3V, 5V.
