LD1117 Adjustable and fixed low drop positive voltage regulator Datasheet - production data Description The LD1117 is a low drop voltage regulator able to provide up to 800 mA of output current, available even in adjustable version DPAK (V =1.25V). Concerning fixed versions, are REF offered the following output voltages: 1.2 V, 1.8 V, TO-220 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 SOT-223 SO-8 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 Features flows mostly into the load. Only a very common 10 µF minimum capacitor is needed for stability. • Low dropout voltage (1 V typ.) On chip trimming allows the regulator to reach a • 2.85 V device performances are suitable for very tight output voltage tolerance, within ± 1 % at SCSI-2 active termination 25 °C. The adjustable LD1117 is pin to pin • Output current up to 800 mA compatible with the other standard. Adjustable voltage regulators maintaining the better • Fixed output voltage of: 1.2 V, 1.8 V, 2.5 V, performances in terms of drop and tolerance. 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.)

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 D I is 1 µA typ. (5 µA max.). ADJ ADJ R is normally fixed to 120 W . 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 kW , 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.
