Product Details
| 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 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. 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. ■ 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: 1.2V, 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 |
