L78
Positive voltage regulator ICs
Datasheet - production data
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.
TO-220
DPAK
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.
TO-220FP
D²PAK
Features
• Output current up to 1.5 A
• Output voltages of 5; 6; 8; 8.5; 9; 12; 15; 18;
24 V
• Thermal overload protection
• Short circuit protection
• Output transition SOA protection
• 2 % output voltage tolerance (A version)
• Guaranteed in extended temperature range
(A version)

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 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.
Figure 8. Fixed output regulator
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.

Figure 27. Protection against input short-circuit with high capacitance loads
Note:
34/58
Application with high capacitance loads and an output voltage greater than 6 volts need an
external diode (see Figure 22 on page 31) 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.
