TL H 7340LM79XX Series 3-Terminal Negative RegulatorsNovember1994LM79XX Series3-Terminal Negative RegulatorsGeneral DescriptionThe LM79XX series of3-terminal regulators is available withfixed output voltages of b5V b8V b12V and b15VThese devices need only one external component a com-pensation capacitor at the output The LM79XX series ispackaged in the TO-220power package and is capable ofsupplying1 5A of output currentThese regulators employ internal current limiting safe areaprotection and thermal shutdown for protection against vir-tually all overload conditionsLow ground pin current of the LM79XX series allows outputvoltage to be easily boosted above the preset value with aresistor divider The low quiescent current drain ofthese devices with a specified maximum change with lineand load ensures good regulation in the voltage boostedmodeFor applications requiring other voltages see LM137datasheetFeaturesY Thermal short circuit and safe area protectionY High ripple

voltage regulator series has thermaloverload protection from excessive power dissipation inter-nal short circuit protection which limits the circuit’s maxi-mum current and output transistor safe-area compensationfor reducing the output current as the voltage across thepass transistor is increasedAlthough the internal power dissipation is limited the junc-tion temperature must be kept below the maximum speci-fied temperature(125 C)in order to meet data sheet specifi-cations To calculate the maximum junction temperature orheat sink required the following thermal resistance valuesshould be

bypass capacitors (2 2m F on the input 1 0m F on theoutput)should be ceramic or solid tantalum which havegood high frequency characteristics If aluminum electrolyt-ics are used their values should be10m F or larger Thebypass capacitors should be mounted with the shortestleads and if possible directly across the regulator termi-nalsHigh Stability1Amp RegulatorTL H 7340–5Load and line regulation

These devices perform the same function as the familiar, bulky, air dielectric stacked capacitors featured in traditional broadcast band receivers.DescriptionThis series of silicon tuning varactors have an epitaxial mesa design with a high temperature passivation. This technology is used to produce abrupt tuning varactor in SOT23 package. This family is designed for a low cost medium to high volume market that may be supplied in tape and reel for automated pick and place assembly on surface mount circuit boards.ApplicationsThe DH71000 series abrupt tuning varactor are offered in a large selection of capacitance range. They provide the highest Q factor (low reverse series resistance) available for a 30 volts silicon device.Typical applications include low noise narrow and moderate frequency bandwidth applications (VCO mainly) from HF to Microwave frequencies (up to 3 GHz). Other applications are voltage tuned ﬁlters, phase shifters, delay line, etc.NOTE : Variation of the junction capacitance versus reverse voltage follows this equation:C j (V r) C j (0 V)1 + V rV r : Reversevoltage φ: Built-in potential .7V for Siγ: .5 for abrupt tuning varactor[ ]SOT23 SURFACE MOUNT SILICON ABRUPT TUNING VARACTORγ=Electrical characteristics at T a = +25°CReverse breakdown voltage, Vb = @10 µA: 30 V min.T emperature ranges:Operating junction (T j): -55°C to +125°C Storage:-65°C to +150°C Packages(1) Other conﬁguration available on request.How to order?DH71010-51T3Diode type Package Conditioninginformation51: single SOT23T3: 3000 pieces53: dual common tape & reelcathode SOT23T10: 10000 pieces54: dual common tape & reelanode SOT23blank: bulk60: single SOD32370: dual SOT143V BR 30VThis series of high Q epi-junction microwave tuning varactors (30 V) incorporates a passivated mesa technology.
