Description

The L78 series of three-terminal positive
regulators is available in TO-220, TO-220FP,
D²PAK and DPAK packages and several fixed
output voltages, making it useful in a wide range
of applications.

These regulators can provide local on-card
regulation, eliminating the distribution problems
associated with single point regulation. Each type
embeds internal current limiting, thermal shut­down and safe area protection, making it
essentially indestructible. If adequate heat
sinking is provided, they can deliver over 1 A
output current. Although designed primarily as
fixed voltage regulators, these devices can be
used with external components to obtain
adjustable voltage and currents.

6 Application information

6.1 Design consideration

The L78 Series of fixed voltage regulators are designed with thermal overload protection
that shuts down the circuit when subjected to an excessive power overload condition,
internal short-circuit protection that limits the maximum current the circuit will pass, and
output transistor safe-area compensation that reduces the output short-circuit current as
the voltage across the pass transistor is increased. In many low current applications,
compensation capacitors are not required. However, it is recommended that the regulator
input be bypassed with capacitor if the regulator is connected to the power supply filter with
long lengths, or if the output load capacitance is large. An input bypass capacitor should be
selected to provide good high frequency characteristics to insure stable operation under all
load conditions. A 0.33 µF or larger tantalum, mylar or other capacitor having low internal
impedance at high frequencies should be chosen. The bypass capacitor should be
mounted with the shortest possible leads directly across the regulators input terminals.
Normally good construction techniques should be used to minimize ground loops and lead
resistance drops since the regulator has no external sense lead.

The addition of an operational amplifier allows adjustment to higher or intermediate values
while retaining regulation characteristics. The minimum voltage obtained with the
arrangement is 2 V greater than the regulator voltage.

The circuit of Figure 13: "High current voltage regulator" can be modified to provide supply
protection against short circuit by adding a short circuit sense resistor, RSC, and an
additional PNP transistor. The current sensing PNP must be able to handle the short circuit
current of the three terminal regulator Therefore a four ampere plastic power transistor is
specified.

1. Although no output capacitor is need for stability, it does improve transient response.

2. Required if regulator is located an appreciable distance from power supply filter.

Q2 is connected as a diode in order to compensate the variation of the Q1 VBE with
the temperature. C allows a slow rise time of the VO.

Application with high capacitance loads and an output voltage greater than 6 volts
need an external diode (see Figure 22: "Reducing power dissipation with dropping

resistor") to protect the device against input short circuit. In this case the input

voltage falls rapidly while the output voltage decrease slowly. The capacitance
discharges by means of the base-emitter junction of the series pass transistor in
the regulator. If the energy is sufficiently high, the transistor may be destroyed.
The external diode by-passes the current from the IC to ground.
