LD1117 SERIES LOW DROP FIXED AND ADJUSTABLE POSITIVE VOLTAGE REGULATORS ■ ■ ■ ■ ■ ■ ■ ■ LOW DROPOUT VOLTAGE (1V TYP.) 2.85V DEVICE PERFORMANCES ARE SUITABLE FOR SCSI-2 ACTIVE TERMINATION OUTPUT CURRENT UP TO 800 mA FIXED OUTPUT VOLTAGE OF: 1.2V, 1.8V, 2.5V, 2.85V, 3.0V, 3.3V, 5.0V ADJUSTABLE VERSION AVAILABILITY (Vrel=1.25V) INTERNAL CURRENT AND THERMAL LIMIT AVAILABLE IN ± 1% (AT 25°C) AND 2% IN FULL TEMPERATURE RANGE SUPPLY VOLTAGE REJECTION: 75dB (TYP.) DESCRIPTION The LD1117 is a LOW DROP Voltage Regulator able to provide up to 800mA of Output Current, available even in adjustable version (Vref=1.25V). Concerning fixed versions, are offered the following Output Voltages: 1.2V,1.8V,2.5V,2.85V, 3.0V 3.3V and 5.0V. The 2.85V type is ideal for SCSI-2 lines active termination. The device is supplied in: SOT-223, DPAK, SO-8, TO-220 and TO-220FM. 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 TO-220FM DPAK TO-220 SOT-223 SO-8 pass transistor. In fact in this case, unlike than PNP one, the Quiescent Current flows mostly into the load. Only a very common 10µF 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.

IADJ is 60µA typ. (120µA max.) and ∆IADJ is 1µA typ. (5µA max.). R1 is normally fixed to 120Ω. From figure 7 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 Kohm, so the R2 x IDJ 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 10µF electrolytic capacitor placed in parallel to the R2 resistor (see Fig.8). 14/24 LD1117 SERIES Figure 7 : Adjustable Output Voltage Application Figure 8 : Adjustable Output Voltage Application with improved Ripple Rejection 15/24 LD1117 SERIES SOT-223 MECHANICAL DATA mm. mils DIM.
