LM2931, NCV2931 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.

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.

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

The input bypass capacitor C is recommended if the

temperature must be observed.

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

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

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

DEFINITIONS

Dropout Voltage − The input/output voltage differential

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.

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.
