DESCRIPTION
The UTC LD1117/A is a LOW DROP Voltage
Regulator able to provide up to 0.8/1.0A of Output Current, available even in adjustable version (Vref=1.25V). Concerning fixed versions, are offered the following Output Voltages: 1.8V, 2.5V, 2.85V, 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, TO-252, TO-263, TO-263-3, SOP-8 and TO-220. The SOT-223, TO-263, TO-263-3 and TO-252 surface mount packages optimize the thermal characteristics even offering a relevant space saving effect. High efficiency is assured by
NPN pass
transistor. In fact in the 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 ±1% at 25°C. The ADJUSTABLE LD1117/A is pin to pin compatible with the other standard Adjustable voltage
regulators maintaining the better performances in terms of Drop and Tolerance.
