LD1117 Adjustable and fixed low drop positive voltage regulator Datasheet - production data 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. DPAK TO-220 SOT-223 SO-8 Features • Low dropout voltage (1 V typ.) • 2.85 V device performances are suitable for SCSI-2 active termination • Output current up to 800 mA • Fixed output voltage of: 1.2 V, 1.8 V, 2.5 V, 3.3 V, 5.0 V • Adjustable version availability (VREF = 1.25 V) • Internal current and thermal limit • Available in ± 1 % (at 25 °C) and 2 % in full temperature range • Supply voltage rejection: 75 dB (typ.) Description The LD1117 is a low drop voltage regulator able to provide up to 800 mA of output current, available even in adjustable version (VREF = 1.25 V). Concerning fixed versions, are offered the following output voltages: 1.2 V, 1.8 V, 2.5 V, 2.85 V, 3.3 V and 5.0 V. The device is supplied in: SOT-223, DPAK, SO-8 and TO-220. The SOT223 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 November 2013 This is information on a product in full production. DocID2572 Rev 33 1/44 www.st.com 44 PDF
