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.
FEATURES
*Low dropout voltage (1V Typ.)
*2.85V device performances are suitable for SCSI-2 active
termination
*Output current up to 0.8/1.0A
*Fixed output voltage of: 1.5V, 1.8V, 2.5V, 2,85V, 3.0V, 3.3V,
*
3.6V, 5.0V
*Adjustable version availability (Vref=1.25V)
*Internal current and thermal limit
*Available in ±1%(at 25°C) and 2% in all temperature range
*Supply voltage rejection: 75dB (TYP)
*Temperature range: 0°C to 125°C
is assured by NPN pass transistor. In fact in the case, unlike
than PNP one, the Quiescent Current flows mostly into the

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
