GENERAL DESCRIPTION
The TCL1117 is a low-dropout positive voltage regula-
tor (LDO) with 800mA output current capability. It is available
in fixed and adjustable output voltage versions, 2.85V (ac-
tive SCSI terminators), 3.30V and 5.00V. Output/reference
voltage accuracy is guaranteed to
±
1.0%. 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 (<100mA). The SOT-223 package makes
the TCL1117 especially attractive for tight physical layouts.
For stability, a 10
μ
F output capacitor is required. The
TCL1117 is an NPN-based design which has significantly
lower unused quiescent current than similar PNP-based
regulators.
