Low drop adjustable positive voltage regulator - BA1117FP
The BA1117FP is a low drop voltage regulator able to provide up to 1 A of output current, available in adjustable versions (VREF=1.25V). The device is supplied in: TO252-3 and TO220-3. Surface mounted packages optimize the thermal characteristics while offering a relevant space saving advantage. High efficiency is assured by NPN pass transistor. Only a very common 22uF minimum capacitor is needed for stability. Chip trimming allows the regulator to reach a very tight reference voltage tolerance, within ±1% at 25?.
