BA1117FP, Low drop adjustable positive voltage regulator

Low drop adjustable positive voltage regulator BA1117FP *

Features

* Low dropout voltage: - 1.2 V typ. (at IO = 1 A, 25℃)
* Output current up to 1 A
* Adjustable version availability (VREF = 1.25 V)
* Internal current and thermal limit
* Available in ±1% (at 25℃) and 2% in full temperature range
* High supply voltage

Applications

* the R2 value is in the range of a few kΩ, so the R2 × IADJ product can not be considered in the VO calculation; the above expression then becomes: VO = 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 particu
