DESCRIPTION
The LM1085 series of positive adjustable and fixed regulators are designed to provide 3A with high efficient.
All internal circuitry is designed to operate down to 1.5V 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
LM1085-3.3V
LM1085-ADJ
Note
(1) C1 needed if device is far away from filter capacitors.
(2) C2 minimum value required for stability
VREF=VOUT-VADJ=1.25V(Typ.)
IADJ=55㎂(Typ.)
VOUT = VREF x (1+RF2/RF1) + IADJ x RF2
