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 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

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.
