Order this document by LM2931/D LOW DROPOUT VOLTAGE REGULATORS 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 * * * * * * * * * * FIXED OUTPUT VOLTAGE Z SUFFIX PLASTIC PACKAGE CASE 29 1 2 Pin 1.

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 . This limit must be observed over the entire operating temperature range of the regulator circuit. MOTOROLA ANALOG IC DEVICE DATA With economical electrolytic capacitors, cold temperature operation can pose a serious stability problem. As the electrolyte freezes, around - 30C, 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 +85C and - 55 to +105C 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. 7 LM2931 Series Figure 17.

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. 10 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 Stabliity - Output voltage stability under accelerated life test conditions with the maximum rated voltage listed in the devices electrical characteristics and maximum power dissipation.
