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: 1.8V, 2.5V, 2.85V, 3.3V and 5.0V. The 2.85V type is ideal for SCSI-2 lines active termination. The device is supplied in:SOT-223, DPAK and TO-220. The surface mount packages optimize the thermal characteristics even offering a relevant space saving effect. High efficiency is assured by NPN pass transistor.

■ LOW DROPOUT VOLTAGE (1.15V TYP. @ IOUT=1A,25°C)
■ VERY LOW QUIESCENT CURRENT (5 mA TYP. @ 25°C)
■ OUTPUT CURRENT UP TO 1A
■ FIXED OUTPUT VOLTAGE OF: 1.8V, 2.5V, 2.85V, 3.3V, 5.0V
■ ADJUSTABLE VERSION AVAILABILITY (Vrel= 1.25V)
■ INTERNAL CURRENT AND THERMAL LIMIT
■ ONLY 10 µF FOR STABILITY
■ AVAILABLE IN ± 2% (AT 25°C) AND 4% IN FULL TEMPERATURE RANGE
■ HIGH SUPPLY VOLTAGE REJECTION: (80dB TYP. AT 25°C)
■ TEMPERATURE RANGE: 0°C TO 125°C
