Adjustable and fixed low drop positive voltage regulator

1 This is information on a product in full production. February 2020 DocID2572 Rev 371/4646LD1117 Adjustable and fixed low drop positive voltage regulatorDatasheet - production dataFeatures Low dropout voltage (1 V typ.) V device performances are suitable for SCSI-2 active termination Output current up to 800 mA fixed output voltage of: V, V, V, V, V Adjustable version availability (VREF = V) Internal current and thermal limit Available in 1 % (at 25 C) and 2 % in full temperature range Supply voltage rejection: 75 dB (typ.)DescriptionThe LD1117 is a low drop voltage regulator able to provide up to 800 mA of output current, available even in Adjustable version (VREF= V).

2 Concerning fixed versions, are offered the following output voltages: V, V, V, V, V and V. 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 F 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.
