LM196/LM396 10 Amp Adjustable Voltage Regulator

General Description

The LM196 is a 10 amp regulator, adjustable from 1.25V to

15V, which uses a revolutionary new IC fabrication structure

to combine high power discrete transistor technology with

modern monolithic linear IC processing. This combination

yields a high-performance single-chip regulator capable of

supplying in excess of 10 amps and operating at power lev-

els up to 70 watts. The regulators feature on-chip trimming

The LM196 is exceptionally easy to use. Only two external

resistors are used to to set output voltage. On-chip adjust-

ment of the reference voltage allows a much tighter specifi-

cation of output voltage, eliminating any need for trimming in

most cases. The regulator will tolerate an extremely wide

range of reactive loads, and does not depend on external

capacitors for frequency stabilization. Heat sink require-

ments are much less stringent, because overload situations

do not have to be accounted forÐonly worst-case full load

conditions.

of reference voltage to 0.8% and simultaneous trimming

of reference temperature drift to 30 ppm/ C typical. Thermal

interaction between control circuitry and the pass transistor

which affects the output voltage has been reduced to ex-

tremely low levels by strict attention to isothermal layout.

This interaction, called thermal regulation, is 100% tested.

The LM196 is in a TO-3 package with oversized (0.060

)

leads to provide best possible load regulation. Operating

junction temperature range is

55 C to

150 C. The

LM396 is specified for a 0 C to 125 C junction tempera-

These new regulators have all the protection features of

popular lower power adjustable regulators such as LM117

and LM138, including current limiting and thermal limiting.

The combination of these features makes the LM196 im-

mune to blowout from output overloads or shorts, even if

the adjustment pin is accidentally disconnected. All devices

are ‘‘burned-in’’ in thermal shutdown to guarantee proper

operation of these protective features under actual overload

conditions.

ture range.

Features

Output pre-trimmed to 0.8%

10A guaranteed output current

P^aProduct Enhancement tested

70W maximum power dissipation

Adjustable outputÐ1.25V to 15V

Internal current and power limiting

Guaranteed thermal resistance

Output voltage is continuously adjustable from 1.25V to

15V. Higher output voltages are possible if the maximum

input-output voltage differential specification is not exceed-

ed. Full load current of 10A is available at all output volt-

ages, subject only to the maximum power limit of 70W and

of course, maximum junction temperature.

Output voltage guaranteed under worst-case conditions

Output is short circuit protected

(R2)

**R2 should be same type as R1, with TC track-

ing of 30 ppm/ C or better.

C1 is necessary only if main filter capacitor is

more than 6 away, assuming 18 or larger

leads.

²²

C2 is not absolutely necessary, but is suggest-

ed to lower high frequency output impedance.

Output capacitors in the range of

1 mF to

1000 mF of aluminum or tantalum electrolytic

are commonly used to provide improved out-

put impedance and rejection of transients.

C3 improves ripple rejection, output imped-

ance, and noise. C2 should be 1 mF or larger

close to the regulator if C3 is used.
