LD2117A - LOW DROP FIXED AND ADJUSTABLE POSITIVE VOLTAGE REGULATORS

Download the LD2117A datasheet PDF. This datasheet also covers the LD2117 variant, as both devices belong to the same low drop fixed and adjustable positive voltage regulators family and are provided as variant models within a single manufacturer datasheet.

General Description

The UTC LD2117/A is a low dropout, 3-terminal positive voltage regulator designed to provide output current up to 800mA/1A, There are adjustable versions (VREF=1.25V) and various fixed versions.

Key Features

  • S.
  • Low dropout voltage.
  • Suitable for SCSI-2 active termination if VOUT set to 2.85V.
  • Output current up to 0.8A for LD2117 and 1.0A for LD2117A.
  • Built-in current limit and over temperature protection.
  • Available in ±1%(at 25°C) and 2% in all temperature range.
  • Ultra low current consumption (0.35mA typ. ).
  • Ultra low Adjustment Current (7μA typ. ).
  • Ultra low minimum Load (0.3mA typ. ).
  • Stable with low ESR ceramic output capacitor (MLCC).
