DESCRIPTION  
SOT-223  
The UTC LD2117/A is a low dropout, 3-terminal positive  
voltage regulator designed to provide output current up to  
800mA/1A, There are adjustable versions (VREF=1.25V) and  
various fixed versions.  
„
FEATURES  
* Low dropout voltage  
* Suitable for SCSI-2 active termination if VOUT set to 2.85V  
* Output current up to 0.8A for 2117 and 1.0A for 2117A  
* Built-in current limit and over temperature protection  
* Available in ±1%(at 25°C) and 2% in all temperature range  
* Ultra low current consumption (0.35mA typ.)  
* Ultra low Adjustment Current (7μA typ.)  
* Ultra low minimum Load (0.3mA typ.)  
* Stable with low ESR ceramic output capacitor (MLCC)

LD2117/A  
LINEAR INTEGRATED CIRCUIT  
„
APPLICATION NOTE of LD2117/A ADJUSTABLE  
The LD2117/A adjustable has a reference voltage of between the OUT and ADJ pins. IADJ is 7μA typ. (10μA  
max.) and ΔIADJ is 0.3μA typ. (2µA max.).  
R1 is normally fixed to 1.2kΩ.  
From figure 4 we obtain:  
VOUT=VREF+R2(IADJ+IR1)=VREF + R2(IADJ+VREF/R1)=VREF(1+R2/R1) + R2 × IADJ.  
Usually R2 value is in the range of few KΩ, so the R2 X IADJ product could be neglected; then the above  
expression becomes: VOUT=VREF(1+R2/R1)  
For better load regulation, realize a good Kelvin connection of R1 and R2 is important. Particularly R1 connection  
must be realized very close to OUT and ADJ pin, while R2 ground connection must be placed as near as possible to  
the negative Load pin. Ripple rejection can be improved by introducing a 10μF electrolytic capacitor placed in  
parallel to the R2 resistor (See Fig. 5)  
The UTC LD2117/A also supports MLCC. See Fig.6 for adjustable output and Fig.7 for fixed Output
