DESCRIPTION
The LD1117A is a LOW DROP Voltage Regulator
able to provide up to 1A 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, 3.3V and 5.0V. The 2.85V type is ideal for
SCSI-2 lines active termination. The device is

TO-220. Surface mount packages optimize the
thermal characteristics even offering a relevant
space saving effect. High efficiency is assured by
NPN pass transistor. Only a very common 10µF
minimum capacitor is needed for stability. Only
chip trimming allows the regulator to reach a very
tight output voltage tolerance, within ± 2% at 25°C.
