GENERAL DESCRIPTION

The TCL1117 is a low-dropout positive voltage regulator (LDO) with 800mA output current capability. It is available in fixed and adjustable output voltage versions, 2.85V (active SCSI terminators), 3.30V and 5.00V. Output/reference voltage accuracy is guaranteed to ¡À1.0. Over-current protection is integrated onto the chip. Dropout is specified at 1.2V maximum at full rated output current and less than 1.0V at low loads (
