3-Amp Adjustable Regulators
General DescriptionThe LM150 seriesof adjustable 3-terminal positive voltage
regulatorsis capableof supplyingin excessof3A overa
1.2Vto 33V output range. Theyare exceptionally easyto
useand require only2 external resistorstosetthe output
voltage. Further, bothline and load regulationare compa-
rableto discrete designs. Also,the LM150is packagedin
standard transistor packages whichare easily mountedand
handled. additionto higher performance than fixed regulators,the
LM150 series offersfull overload protection available onlyin
IC’s. Includedonthechipare current limit, thermal overload
protectionand safe area protection.All overload protection
circuitry remainsfully functional evenif theadjustment termi-
nalis accidentally disconnected.
Normally,no capacitorsare needed unless thedeviceis situ-
ated more than6 inches fromthe input filter capacitorsin
which casean input bypassis needed.An output capacitor
canbe addedto improve transient response, while bypass-
ingthe adjustmentpinwill increasethe regulator’s ripplere-
jection.
Besides replacing fixed regulatorsor discrete designs,the
LM150 isusefulina wide varietyof other applications. Since
the regulatoris “floating” and sees onlythe input-to-output
differential voltage, suppliesof several hundred voltscanbe
regulatedaslongasthe maximum inputto output differentialnot exceeded,i.e., avoid short-circuitingthe output. connectinga fixed resistor betweenthe adjustmentpin
and output,the LM150canbe usedasa precision current
regulator. Supplies with electronic shutdown can be
achievedby clampingthe adjustment terminalto ground
which programsthe outputto 1.2V where most loads draw
little current.
Thepart numbers inthe LM150series which havea Ksuffix
are packagedina standard SteelTO-3 package, while those
withaT suffixare packagedina TO-220 plastic package.
The LM150is ratedfor −55˚C≤TJ≤ +150˚C, whilethe
LM350Ais ratedfor −40˚C≤TJ≤ +125˚C,andthe LM350is
ratedfor0˚C≤TJ≤ +125˚C.
