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.
