LOW DROP FIXED AND ADJUSTABLE POSITIVE VOLTAGE REGULATORS
1/28October 2004 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
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.
