LT1086 Series

1.5A Low Dropout Positive

Regulators Adjustable and

Fixed 2.85V, 3.3V, 3.6V, 5V, 12V

FEATURES

DESCRIPTIO

The LT^®1086 is designed to provide up to 1.5A output

current. All internal circuitry is designed to operate down

to 1V input-to-output differential and the dropout voltage

is fully specified as a function of load current. Dropout is

■

3-Terminal Adjustable or Fixed

2.85V, 3.3V, 3.6V, 5V, 12V

■

Output Current of 1.5A (0.5A for LT1086H)

■

Operates Down to 1V Dropout

■

Guaranteed Dropout Voltage at Multiple Current Levels guaranteed at several operating points up to a maximum

■

Line Regulation: 0.015%

of 1.5V at maximum output current. Dropout decreases at

lower load currents. On-chip trimming adjusts the refer-

ence/ouput voltage to 1%. Current limit is also trimmed,

minimizing the stress on both the regulator and power

source circuitry under overload conditions.

Load Regulation: 0.1%

100% Thermal Limit Functional Test

Ripple Rejection >75dB

Available in 3-Pin TO-220 and 3-Pin DD Packages

TheLT1086ispincompatiblewitholder3-terminaladjust-

able regulators. A minimum 10µF output capacitor is

required on these devices.

SCSI-2 Active Terminator

TheLT1086offersexcellentlineandloadregulationspeci-

fications and ripple rejection exceeds 75dB even at the

maximum load current of 1.5A. The LT1086 is floating

architecture with a composite NPN output stage. All of the

quiescent current and the drive current for the output

stage flows to the load increasing efficiency.
