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 DPAK compatible with the other standard. Adjustable voltage regulators maintaining the better TO-220 performances in terms of drop and tolerance. 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, 3.3V, 5.0 V • Adjustable version availability (V = 1.25 V) REF • 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 (V = REF 1.25V). 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 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 November 2013 DocID2572 Rev 33 1/44 This is information on a product in full production. www.st.com 44

LD1117 adjustable: application note LD1117 7 LD1117 adjustable: application note The LD1117 adjustable has a thermal stabilized 1.25 ± 0.012 V reference voltage between the OUT and ADJ pins. I is 60 µA typ. (120 µA max.) and ΔI is 1 µA typ. (5 µA max.). ADJ ADJ R is normally fixed to 120 Ω. From Figure9 we obtain: 1 V = V + R (I +I ) = V + R (I +V /R ) = V (1 + R / R ) + R x I . OUT REF 2 ADJ R1 REF 2 ADJ REF 1 REF 2 1 2 ADJ In normal application R value is in the range of few kΩ, so the R x I product could not 2 2 ADJ be considered in the V calculation; then the above expression becomes: OUT V = V (1 + R / R ). OUT REF 2 1 In order to have the better load regulation it is important to realize a good Kelvin connection of R and R resistors. In particular R connection must be realized very close to OUT and 1 2 1 ADJ pin, while R ground connection must be placed as near as possible to the negative 2 Load pin. Ripple rejection can be improved by introducing a 10 µF electrolytic capacitor placed in parallel to the R resistor (see Figure10). 2 Figure 10. Adjustable output voltage application Figure 11.
