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

V_REF=V_OUT-V_ADJ=1.25V(Typ.)

(1) C1 needed if device is far away from filter capacitors.

(2) C2 minimum value required for stability

I_ADJ=55㎂(Typ.)

V_OUT= V_REFx (1+RF2/RF1) + I_ADJx RF2
