LD1117xx Low drop fixed and adjustable positive voltage regulators 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, 2.85 V, 3.0 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.) DPAK TO-220 SOT-223 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, 3.0 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. SO-8 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 10F minimum capacitor is needed for stability. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within 1% at 25C. 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. The SOT-223 and DPAK surface mount packages optimize the thermal characteristics even offering a relevant space saving effect. Table 1.

Post-regulated dual supply 25/41 LD1117 adjustable: application note 7 LD1117xx LD1117 adjustable: application note The LD1117 Adjustable has a thermal stabilized 1.25 0.012 V reference voltage between the OUT and ADJ pins. IADJ is 60 A typ. (120 A max.) and IADJ is 1 A typ. (5 A max.). R1 is normally fixed to 120 . From Figure 10 we obtain: VOUT = VREF + R2 (IADJ +IR1) = VREF + R2 (IADJ +VREF /R1) = VREF (1 + R2 / R1) + R2 x IADJ. In normal application R2 value is in the range of few k, so the R2 x IADJ product could not be considered in the VOUT calculation; then the above expression becomes: VOUT = VREF (1 + R2 / R1). In order to have the better load regulation it is important to realize a good Kelvin connection of R1 and R2 resistors. In particular R1 connection must be realized very close to OUT and ADJ pin, while R2 ground connection must be placed as near as possible to the negative Load pin. Ripple rejection can be improved by introducing a 10 F electrolytic capacitor placed in parallel to the R2 resistor (see Figure 11). Figure 11. Adjustable output voltage application Figure 12.
