TEMPERATURE RANGE: 0°C TO 125°C  
DPAK  
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.  
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
