Features

* Low dropout voltage:
* 1.15 V typ. @ IOUT = 1 A, 25 °C
* Very low quiescent current:
* 5 mA typ. @ 25 °C
* Output current up to 1 A The LD1117A is a low drop voltage regulator able to provide up to 1 A of output current, available also in adjustable version

Applications

* the R2 value is in the range of a few kΩ, so the R2 x IADJ product can not be considered in the VOUT calculation; the above expression then becomes: VOUT = VREF (1 + R2 / R1). In order to have a better load regulation it is important to realize a good Kelvin connection of R1 and R2 resistors. In par
