Description
The LD1117 is a low drop voltage regulator able to provide up to 800 mA of output current,
available even in adjustable version (V REF = 1.25 V). Concerning fixed versions, are offered the following output voltages: 1.2 V , 1.8 V, 2.5 V, 2.85 V , 3.0 V , 3.3 V and 5.0 V . The 2.85 V type is ideal for SCSI-2 lines active termination. The device is supplied in: SOT -223, DPAK, SO-8 and TO-220.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 pass transistor. In fact in this case, unlike than PNP one, the
quiescent current flows mostly into the load. Only a very common 10 μF 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 is pin to pin compatible with the other standard. Adjustable voltage regulators
maintaining the better performances in terms of drop and tolerance.
