All internal circuitry is designed to operate down to 1.3V input to output differential. On-chip trimming adjusts the reference voltage to 1%. It's low dropout voltage and fast transient response make it ideal for low voltage microprocessor applications. Internal current and thermal limiting provides protection against any overload condition that would create excessive junction temperature. TEST & TYPICAL APPLICATION CIRCUIT Note (1) C1 needed if device is far away from filter capacitors. VREF=VOUT-VADJ=1.25V(Typ.) IADJ=55㎂(Typ.) (2) C2 minimum value required for stability. VOUT = VREF x (1+RF2/RF1) + IADJ x RF2 Nov. 2010 - Rev. 1.3. HTC - 1 - Device Package LM1084RS-X.X TO-252 3LD TO-263 3LD LM1084R-X.X TO-263 PKG LM1084-3.3V LM1084-ADJ TO-252 PKG |
