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
T h e s e 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.
