LD1117/A
LINEAR INTEGRATED CIRCUIT
LOW DROP FIXED AND
ADJUSTABLE POSITIVE
VOLTAGE REGULATORS
DESCRIPTION
The UTC LD1117/A is a low dropout, 3-terminal positive
voltage regulator designed to provide output current up to
800mA/1A, There are adjustable version (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 1117 and 1.0A for 1117A
* Built-in current limit and over temperature protection
* Available in ±1%(at 25°C) and 2% in all temperature range
* Low current consumption
*Pb-free plating product number:
LD1117L-xx / LD1117AL-xx

LINEAR INTEGRATED CIRCUIT
APPLICATION NOTE of LD1117/A ADJUSTABLE
The LD1117/A ADJUSTABLE has a reference voltage of between the OUT and ADJ pins. IADJ is 60µA typ.
(120µA max.) and ∆IADJ is 1µA typ. (5µA max.).
R1 is normally fixed to 120Ω.
From figure 4 we obtain:
VOUT=VREF+R2(IADJ + IR1)=VREF + R2(IADJ + VREF / R1)=VREF(1+R2/R1) + R2 x 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)
