LM150/LM350A/LM350 3-Amp Adjustable Regulators

Check for Samples: LM150, LM350-N, LM350A

In addition to higher performance than fixed

FEATURES

regulators, the LM150 series offers full overload

protection available only in IC's. Included on the chip

are current limit, thermal overload protection and safe

area protection. All overload protection circuitry

remains fully functional even if the adjustment

terminal is accidentally disconnected.

Adjustable Output Down to 1.2V

Guaranteed 3A output Current

Guaranteed Thermal Regulation

Output is Short Circuit Protected

Current Limit Constant with Temperature

P⁺Product Enhancement Tested

86 dB Ripple Rejection

Normally, no capacitors are needed unless the device

is situated more than 6 inches from the input filter

capacitors in which case an input bypass is needed.

An output capacitor can be added to improve

transient response, while bypassing the adjustment

pin will increase the regulator's ripple rejection.

Ensured Max. 0.01%/V Line Regulation

(LM350A)

Besides replacing fixed regulators or discrete

designs, the LM150 is useful in a wide variety of

other applications. Since the regulator is “floating”

and sees only the input-to-output differential voltage,

supplies of several hundred volts can be regulated as

long as the maximum input to output differential is not

exceeded, i.e., avoid short-circuiting the output.

Ensured Max. 0.3% Load Regulation (LM350A)

APPLICATIONS

•

Adjustable Power supplies

Constant Current Regulators

Battery Chargers

By connecting

adjustment pin and output, the LM150 can be used

as precision current regulator. Supplies with

fixed resistor between the

DESCRIPTION

electronic shutdown can be achieved by clamping the

adjustment terminal to ground which programs the

output to 1.2V where most loads draw little current.

The LM150 series of adjustable 3-terminal positive

voltage regulators is capable of supplying in excess

of 3A over a 1.2V to 33V output range. They are

exceptionally easy to use and require only 2 external

resistors to set the output voltage. Further, both line

and load regulation are comparable to discrete

designs. Also, the LM150 is packaged in standard

transistor packages which are easily mounted and

handled.

The part numbers in the LM150 series which have a

NDS suffix are packaged in a standard Steel TO-3

package, while those with a NDE suffix are packaged

in a TO-220 plastic package. The LM150 is rated for

−55°C ≤ T_J≤ +150°C, while the LM350A is rated for

−40°C ≤ T_J≤ +125°C, and the LM350 is rated for 0°C

≤ T_J≤ +125°C.
