LD1117A series  
Low drop fixed and adjustable positive voltage regulators  
Features  
Low dropout voltage  
(1.15V typ. @ IOUT = 1A, 25°C)  
Very low quiescent current  
(5 mA typ. @ 25°C)  
SOT-223  
D2PAK/A  
Output current up to 1A  
TO-220  
DPAK  
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  
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, D2PAK/A and TO-220. Surface  
mount packages optimize the thermal  
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  
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).
