LM2931 Series 100 mA, Adjustable Output, LDO Voltage Regulator with 60 V Load Dump Protection The LM2931 series consists of positive fixed and adjustable output voltage regulators that are specifically designed to maintain proper regulation with an extremely low input–to–output voltage differential. These devices are capable of supplying output currents in excess of 100 mA and feature a low bias current of 0.4 mA at 10 mA output. Designed primarily to survive in the harsh automotive environment, these devices will protect all external load circuitry from input fault conditions caused by reverse battery connection, two battery jump starts, and excessive line transients during load dump. This series also includes internal current limiting, thermal shutdown, and additionally, is able to withstand temporary power–up with mirror–image insertion. Due to the low dropout voltage and bias current specifications, the LM2931 series is ideally suited for battery powered industrial and consumer equipment where an extension of useful battery life is desirable. The ‘C’ suffix adjustable output regulators feature an output inhibit pin which is extremely useful in microprocessor–based systems. • Input–to–Output Voltage Differential of < 0.6 V @ 100 mA • Output Current in Excess of 100 mA • Low Bias Current • 60 V Load Dump Protection • –50 V Reverse Transient Protection • Internal Current Limiting with Thermal Shutdown • Temporary Mirror–Image Protection • Ideally Suited for Battery Powered Equipment • Economical 5–Lead TO–220 Package with Two Optional Leadforms • Available in Surface Mount SOP–8, D2PAK and DPAK Packages • High Accuracy (±2%) Reference (LM2931AC) Available http://onsemi.com FIXED OUTPUT VOLTAGE TO–92 Z SUFFIX CASE 29 Pin 1.

Output Inhibit–Thresholds versus Output Voltage APPLICATIONS INFORMATION The LM2931 series regulators are designed with many protection features making them essentially blow–out proof. These features include internal current limiting, thermal shutdown, overvoltage and reverse polarity input protection, and the capability to withstand temporary power–up with mirror–image insertion. Typical application circuits for the fixed and adjustable output device are shown in Figures 17 and 18. The input bypass capacitor Cin is recommended if the regulator is located an appreciable distance (≥ 4″) from the supply input filter. This will reduce the circuit’s sensitivity to the input line impedance at high frequencies. This regulator series is not internally compensated and thus requires an external output capacitor for stability. The capacitance value required is dependent upon the load current, output voltage for the adjustable regulator, and the type of capacitor selected. The least stable condition is encountered at maximum load current and minimum output voltage. Figure 22 shows that for operation in the “Stable” region, under the conditions specified, the magnitude of the output capacitor impedance |ZO| must not exceed 0.4 Ω. This limit must be observed over the entire operating temperature range of the regulator circuit. With economical electrolytic capacitors, cold temperature operation can pose a serious stability problem. As the electrolyte freezes, around –30°C, the capacitance will decrease and the equivalent series resistance (ESR) will increase drastically, causing the circuit to oscillate. Quality electrolytic capacitors with extended temperature ranges of –40° to +85°C and –55° to +105°C are readily available. Solid tantalum capacitors may be a better choice if small size is a requirement, however, the maximum ZO limit over temperature must be observed. Note that in the stable region, the output noise voltage is linearly proportional to ZO. In effect, CO dictates the high frequency roll–off point of the circuit. Operation in the area titled “Marginally Stable” will cause the output of the regulator to exhibit random bursts of oscillation that decay in an under–damped fashion. Continuous oscillation occurs when operating in the area titled “Unstable”. It is suggested that oven testing of the entire circuit be performed with maximum load, minimum input voltage, and minimum ambient temperature. http://onsemi.com 8 LM2931 Series Input Vin 51 k Cin 0.1 LM2931C Adjustable Output Output Inhibit 2 Output 1 LM2931-5.0 Fixed Output Input Cin 0.1 Output R V out V 1 2 I R 2 ref Adj R1 22.5k R 1R 2 R 1 R 2 Figure 18.

The D45VH7, on a heatsink, will provide an output current of 5.0 A with an input to output voltage differential of approximately 1.0 V. Resistor R in conjunction with the VBE of the PNP determines when the pass transistor begins conducting. This circuit is not short circuit proof. The circuit of Figure 19 can be modified to provide supply protection against short circuits by adding the current sense resistor RSC and an additional PNP transistor. The current sensing PNP must be capable of handling the short circuit current of the LM2931. Safe operating area of both transistors must be considered under worst case conditions. Figure 19.

Copper Length LM2931 Series DEFINITIONS Maximum Power Dissipation – The maximum total device dissipation for which the regulator will operate within specifications. Bias Current – That part of the input current that is not delivered to the load. Output Noise Voltage – The rms AC voltage at the output, with constant load and no input ripple, measured over a specified frequency range. Long–Term Stability – Output voltage stability under accelerated life test conditions with the maximum rated voltage listed in the devices electrical characteristics and maximum power dissipation. Dropout Voltage – The input/output voltage differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the output decreases 100 mV from nominal value at 14 V input, dropout voltage is affected by junction temperature and load current. Line Regulation – The change in output voltage for a change in the input voltage. The measurement is made under conditions of low dissipation or by using pulse techniques such that the average chip temperature is not significantly affected. Load Regulation – The change in output voltage for a change in load current at constant chip temperature. http://onsemi.com 11 LM2931 Series ORDERING INFORMATION Output Device Voltage Tolerance Package Shipping LM2931AD–5.0 SOIC–8 98 Units/Rail LM2931AD–5.0R2 SOIC–8 2500 Tape & Reel NCV2931AD–5.0R2* SOIC–8 2500 Tape & Reel LM2931ADT–5.0 DPAK 75 Units/Rail LM2931ADT–5.0RK DPAK 2500 VacPk Reel D2PAK 50 Units/Rail LM2931AD2T–5.0R4 D2PAK 800 VacPk Reel LM2931AT–5.0 TO–220 50 Units/Rail LM2931AZ–5.0 TO–92 2000/Inner Bag TO–92 2000 Tape & Reel TO–92 2000/Ammo Pack LM2931D–5.0 SOIC–8 98 Units/Rail LM2931D–5.0R2 SOIC–8 2500 Tape & Reel LM2931D2T–5.0 D2PAK 50 Units/Rail LM2931D2T–5.0R4 D2PAK 800 VacPk Reel 3.8% LM2931AD2T–5.0 LM2931AZ–5.0RA LM2931AZ–5.0RP 50V 5.0 LM2931DT–5.0 DPAK 75 Units/Rail TO–220 50 Units/Rail TO–92 2000/Inner Bag TO–92 2000 Tape & Reel LM2931Z–5.0RP TO–92 2000/Ammo Pack LM2931CD SOIC–8 98 Units/Rail LM2931CDR2 SOIC–8 2500 Tape & Reel LM2931CD2T D2PAK 50 Units/Rail LM2931CD2TR4 D2PAK 800 VacPk Reel TO–220 50 Units/Rail SOIC–8 98 Units/Rail SOIC–8 2500 Tape & Reel D2PAK 800 VacPk Reel TO–220 50 Units/Rail LM2931T–5.0 LM2931Z–5.0 5 0% 5.0% LM2931Z–5.0RA LM2931CT Adjustable j LM2931ACD LM2931ACDR2 LM2931ACD2TR4 2 0% 2.0% LM2931ACTV *NCV2931: Tlow = –40°C, Thigh = +125°C.
