1 / 9 page 1 PRELIMINARY INFORMATION TCL1117-05 6/5/97 800mA LOW DROPOUT POSITIVE REGULATORS ADJUSTABLE AND FIXED 2.85V, 3.30V, 5.00V TCL1117 TCL1117-2.85 TCL1117-3.30 TCL1117-5.00 800mA LOW DROPOUT POSITIVE REGULATORS ADJUSTABLE AND FIXED 2.85V, 3.30V, 5.00V 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 µF output capacitor is required. The TCL1117 is an NPN-based design which has significantly lower unused quiescent current than similar PNP-based regulators.
