LM340/LM78XX Series

3-Terminal Positive Regulators

General Description

The 5V, 12V, and 15V regulator options are available in the

steel TO-3 power package. The LM340A/LM340/LM78XXC

series is available in the TO-220 plastic power package, and

the LM340-5.0 is available in the SOT-223 package, as well

as the LM340-5.0 and LM340-12 in the surface-mount TO-

263 package.

The

LM140/LM340A/LM340/LM78XXC

monolithic

3-terminal positive voltage regulators employ internal

current-limiting, thermal shutdown and safe-area compensa-

tion, making them essentially indestructible. If adequate heat

sinking is provided, they can deliver over 1.0A output cur-

rent. They are intended as fixed voltage regulators in a wide

range of applications including local (on-card) regulation for

elimination of noise and distribution problems associated

with single-point regulation. In addition to use as fixed volt-

age regulators, these devices can be used with external

components to obtain adjustable output voltages and cur-

rents.

Features

n Complete specifications at 1A load

n Output voltage tolerances of 2% at T_j= 25˚C and 4%

over the temperature range (LM340A)

n Line regulation of 0.01% of V_OUT/V of ∆V_INat 1A load

(LM340A)

n Load regulation of 0.3% of V_OUT/A (LM340A)

n Internal thermal overload protection

n Internal short-circuit current limit

n Output transistor safe area protection

n P⁺Product Enhancement tested

Considerable effort was expended to make the entire series

of regulators easy to use and minimize the number of exter-

nal components. It is not necessary to bypass the output,

although this does improve transient response. Input by-

passing is needed only if the regulator is located far from the

filter capacitor of the power supply.

*Required if the regulator is located far from the power supply filter.

load regulation (L ) ≈ [(R1 + R2)/R1] (L of LM340-5).

**Although no output capacitor is needed for stability, it does help transient

response. (If needed, use 0.1 µF, ceramic disc).
