LOW DROP FIXED AND ADJUSTABLE POSITIVE VOLTAGE REGULATORS
DESCRIPTION
The LRC LR1117/A is a LOW DROP Voltage Regulator
able to provide up to
0.8/1.0A
of Output Current, available
even in adjustable version (Vref=1.25V). Concerning fixed
versions, are offered the following Output Voltages: 1.5V,
1.8V, 2.5V, 2.85V, 3.0V, 3.3V, 3.6V and 5.0V. The 2.85V type
is ideal for SCSI-2 lines active termination. High efficiency
is assured by NPN pass transistor. In fact in the case, unlike
than PNP one, the Quiescent Current flows mostly into the
for stability. On chip trimming allows the regulator to reach a
very tight output voltage tolerance, within ±1% at 25°C. The
ADJUSTABLE LR1117/A is pin to pin compatible with the
other standard Adjustable voltage regulators maintaining the
better performances in terms of Drop and Tolerance.

Note:
1.
Absolute Maximum Ratings are those value beyond which damage to the device may occur. Functional
operation under there condition is not implied. Over the above suggested Max Power Dissipation a Short Circuit
could definitively damage the device.

Can EPM240 accommodate 5 serial ports?
I know I sent it to the wrong place, but it's urgent and this is very popular. Please forgive me. Is it okay if DEV_OE and DEV_CLRn are not accepted?...
