OM185-5SM OM186-5SM SURFACE MOUNT LOW DROPOUT FIXED VOLTAGE POSITIVE REGULATORS Three Terminal, +5V, Low Dropout Precision Positive Regulator In Hermetic Surface Mount Package FEATURES • • • • • • +5V Output Voltage Operates Down To 1V Dropout .015% Line Regulation / .01% Load Regulation Typically Output Voltage Trimmed to ±1% Hermetic Surface Mount Package Available Hi-Rel Screened DESCRIPTION These three terminal positive fixed voltage regulators 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. All devices are pin compatible with older three terminal regulators. Supplied in easy-to-use hermetic surface mount packages.

Note 2: Line and load regulation are guaranteed up to the maximum power dissipation (OM185-5/20W, OM186-5/10W). 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.
