BA1117FP

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 rejection: - 75 dB typ. (at 25℃) „ Temperature range: -20℃ to 105℃ „ Designed to use by ceramic capacitors TO252-3 TO220-3 ●Typical Application V IN 10uF ●Description 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℃. V OUT V REF ADJ IADJ R1 22uF R2 VREF = 1.25 V (Typ.) IADJ = 60 uA (Typ.) VO = VREF × (1 + R2 / R1 ) + IADJ × R2 Table1.
