SURFACE MOUNT LOW DROPOUT POSITIVE
ADJUSTABLE REGULATOR
Three Terminal, Adjustable Low Dropout
2.0 Amp And 1.0 Amp Positive
Voltage Regulators
FEATURES
• Hermetic Surface Mount Package
• Operates Down To 1V Dropout, 1.5V @ Max. Current
• .020% Line Regulation Typically
• .050% Load Regulation Typically
• 1% Reference Voltage
• Electrically Equivalent To LT1085 And LT1086
• Available Hi-Rel Screened
DESCRIPTION
These three terminal positive adjustable voltage regulators in a surface mount
package are designed to provide 2.0 Amps and 1.0 Amp with higher efficiency than
conventional voltage regulators. The devices are designed to operate to 1 Volt input
to output differential and the dropout voltage is specified as a function of load current.
These devices are ideally suited for Hi-Rel applications where surface mount, small
size, hermeticity and high reliability are required.

Note 1: Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing.
Note 2: Line and load regulation are guaranteed up to the maximum power dissipation (OM185/20W, OM186/10W).
Power dissipation is determined by the input/output differential and the output current. Guaranteed maximum
power dissipation will not be available over the full input/output voltage range.
Note 3: IFULL LOAD curve is defined as the minimum value of current limit as a function of input to output voltage. Note that
power dissipation is only achievable over a limited range of input to output voltage.
Note 4: Dropout voltage is specified over the full output current range of the device.
The denotes the specifications which apply over the full operating temperature range.
