LOW DROP FIXED AND ADJUSTABLE POSITIVE VOLTAGE REGULATORS

LOW DROPOUT VOLTAGE (1V TYP.) 2.85V DEVICE PERFORMANCES ARE SUITABLE FOR SCSI-2 ACTIVE TERMINATION OUTPUT CURRENT 800 mA FIXED OUTPUT VOLTAGE OF: 3.3V, 5.0V ADJUSTABLE VERSION AVAILABILITY (Vrel=1.25V) INTERNAL CURRENT AND THERMAL LIMIT AVAILABLE ± 1% (AT 25°C) AND 2% IN FULL TEMPERATURE RANGE SUPPLY VOLTAGE REJECTION: 75dB (TYP.)

DESCRIPTION The is a LOW DROP Voltage Regulator able to provide 800mA of Output Current, available even in adjustable version (Vref=1.25V). Concerning fixed versions, are offered the following Output Voltages: 3.0V 3.3V and 5.0V. The 2.85V type is ideal for SCSI-2 lines active termination. The device is supplied in: SOT-223, DPAK, SO-8, TO-220 and TO-220FM. The SOT-223 and DPAK surface mount packages optimize the thermal characteristics even offering a relevant space saving effect. High efficiency is assured by NPN BLOCK DIAGRAM

pass transistor. In fact in this case, unlike than PNP one, the Quiescent Current flows mostly into the load. Only a very common 10µF minimum capacitor is needed for stability. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within at 25°C. The ADJUSTABLE LD1117 is pin to pin compatible with the other standard. Adjustable voltage regulators maintaining the better performances in terms of Drop and Tolerance.

Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is not implied. Over the above suggested Max Power Dissipation a Short Circuit could definitively damage the device.
