D3-Terminal RegulatorsDOutput Current up to 100 mADNo External ComponentsDInternal Thermal-Overload ProtectionDInternal Short-Circuit Current LimitingDProvided Pb-Free packages from the endof 2004descriptionThis series of fixed-voltage integrated-circuitvoltage regulators is designed for a wide range ofapplications. These applications include on-cardregulation for elimination of noise and distributionproblems associated with single-point regulation.In addition, they can be used with power-passelements to make high-current voltage regulators.One of these regulators can deliver up to 100 mAof output current. The internal limiting andthermal-shutdown features of these regulatorsmake them essentially immune to overload. Whenused as a replacement for a zener diode-resistorcombination, an effective improvement in outputimpedance can be obtained, together with lowerbias current.electrical characteristics at specified virtual junction temperature, VI = otherwise noted)PARAMETERTEST CONDITIONST‡UNITMINTYPMAX25°COutput voltage VIO = 1 mA to 70 mAFull rangeInputVI°voltage regulationVI = Ripple rejectionVI = f = 120 Hz25°CdBOutputIO = 1 mA to 100 mA°voltage regulationIO = 1 mA to 40 mAOutputnoise voltagef = 10 Hz to 100 kHz25°CµVDropout voltage25°CV25°C 125°CBiasVI = 1.5current changeIO = 1 mA to 40 mA range0.1‡Pulse-testing techniques maintain TJ as close to TA as possible.
