DESCRIPTION

The C78L00 series is a CMOS Positive Voltage

Regulators. These regulators contains internal pre-

cision voltage reference, error amplifier, control

transistor and output voltage setting resistor.

The regulation voltage is fixed by internal circuits

and the following lines of different output voltages

areavailable.

Thisseriesissuitable forbattery operated itemsand

battery back-up systems because of low current

consumption and low drop out voltage.

(*) Our SO-8 packageused for Voltage Regulators is modified internally to have pins 2, 3, 6 and 7 electrically commoned to the

die attach flag. This particular frame decreases the total thermal resistance of the package and increases its ability to dissipate

power when an appropriate are of copper on the printed circuit board is available for the heatsinking. The external dimensions

are the same as for the standard SO-8

DESCRIPTION

The L7800 series of three-terminal positive regula-

tor is available in TO-220, ISOWATT220 and TO-3

packages and with several fixed output voltages

making it useful in a wide range of applications.

These regulators can provide local on-card regula-

tion, eliminating the distribution problems associ-

atedwithsinglepointregulation. Eachtypeemploys

internal current limiting,thermalshut-down and safe

area protection, making it essentially indestructible.

Ifadequate heatsinkingisprovided, theycandeliver

over 1Aoutput current. Although designedprimarily

as fixed voltage regulators, these devices can be

usedwith external components to obtain adjustable

voltages andcurrents.

DESCRIPTION

The L78L00 series of three-terminal positive regu-

lators employ internal current limiting and thermal

shutdown, making themessentially indestructible. If

adequate heatsink is provided, they can deliver up

to100mAoutputcurrent.Theyareintended asfixed

voltage regulators inawide range of applications in-

cluding local or on-card regulation forelimination of

noise and distribution problems associated with

single-point regulation. Inaddition, they canbeused

withpowerpasselements tomake high-current volt-

age regulators.

The L78L00 series used as Zener diode/resistor

combination replacement, offers an effectiveoutput

impedance improvement of typically two orders of

magnetude, along with lower quiescent current and

lowernoise.

(*) Our SO-8 package used for Voltage Regulators is modified internally to have pins 2, 3, 6 and 7 electrically commoned to

the die attach flag. This particular frame decreases the total thermal resistance of the package and increases its ability to dissi-

pate power when an appropriate area of copper on the printed circuit board is available for heatsinking. The external dimen-

sions are the same as for the standard SO-8

DESCRIPTION

The L78M00 series of three-terminal positive

regulators is available in TO-220, ISOWATT220,

SOT-82, SOT-194 and DPAK packages and with

several fixed output voltages, making it useful in a

wide range of applications. These regulators can

providelocal on-card regulation, eliminating the dis-

tribution problems associated with single point

regulation. Eachtype employsinternal current limit-

ing, thermal shut-down and safe area protection,

making itessentially indestructible. Ifadequate heat

sinking is provided, they can deliver over 0.5A out-

put current. Although designed primarily as fixed

voltage regulators, thesedevices can be used with

external components to obtain adjustable voltages

and currents.

DESCRIPTION

The L78S00series of three-terminal positive regu-

lators is available in TO-220 and TO-3 packages

and with several fixed output voltages, making it

useful in a wide range of applications. These regu-

lators canprovide local on-card regulation, eliminat-

ing the distribution problems associated with single

point regulation. Each type employs internal current

limiting, thermal shut-down and safe area protec-

tion, making it essentially indestructible. Ifadequate

heat sinking is provided, they can deliver over 2A

outputcurrent. Although designed primarily as fixed

voltage regulators, these devices can be used with

external components to obtain adjustable voltages

and currents.

withHigh Capacitance Loads.

Applications with high capacitance loads and an

outputvoltage greater than6 volts need an external

diode(see fig.33) to protectthedeviceagainst input

short circuit. In this case the input voltage falls

rapidly while the output voltage decreases showly.

The capacitance discharges by means of theBase-

Emitter junction of the series pass transistor in the

regulator. If the energy is sufficiently high, the tran-

sistor may be destroyed. The external diode by-

passes thecurrent fromthe ICto ground.

DESCRIPTION

The L7900series of three-terminal negative regula-

torsis available in TO-220 and TO-3 packages and

with several output voltages. They can provide local

on-cardregulation, eliminating the distribution prob-

lemsassociatedwithsinglepoint regulation; further-

more,havingthesamevoltage optionsasthe L7800

positive standard series, they are particularly suited

for split power supplies. In addition, the –5.2Vis

also available for ECL system.

If adeguate heatsinking is provided, the L7900

series can deliver an output current in excess of

1.5A. Although designed primarly as fixed voltage

regulators, thesedevices can be usedwith external

components to obtain adjustable voltages and cur-

rents.

Notes : 1. To specify an output voltage, substitute voltage

value for ”XX”.

2. Required for stability. For value given, capacitor

must be solid tantalum. If aluminium electrolitics

are used, at least ten times value should be se-

lected. C1is required if regulator is located an

appreciable distance from power supply filter.

3. To improve transient response. If large capaci-

tors are used, a high current diode from input to

output (1N4001 or similar) should be introduced

to protect the device from momentary input short

circuit.

*Against potential latch-upproblems.

DESCRIPTION

The L79L00 series of three-terminal negative

regulators employinternal current limiting and ther-

mal shutdown, making them essentially indestruc-

tible. If adequate heatsink is provided, they can

deliver up to 100 mA output current. They are in-

tended as fixed voltage regulators in a wide range

of applications including local or on-card regulation

forelimination ofnoiseand distributionproblems as-

sociated with single-point regulation. In addition,

theycan beusedwithpowerpasselements tomake

high-current voltage regulators.

The L79L00 series used as Zener diode/resistor

combination replacement, offers an effectiveoutput

impedance improvement of typically two orders of

magnetude, along with lower quiescent current and

lowernoise.

(*) Our SO-8 package used for Voltage Regulators is modified internally to have pins 2, 3, 6 and 7 electrically commoned to

the die attach flag. This particular frame decreases the total thermal resistance of the package and increases its ability to dis-

sipate power when an appropriate area of copper on the printed circuit board is available for heatsinking. The external dimen-

sions are the same as for the standard SO-8
