ON LM2931DT.5.0 100 ma, adjustable output, ldo voltage regulator with 60 v load dump protection Datasheet

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.
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 W. 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.

The LM2931 series can be current boosted with a PNP transistor. 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.

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.
