MOTOROLA ANALOG IC DEVICE DATA
The LM350 is an adjustable three–terminal positive voltage regulator
capable of supplying in excess of 3.0 A over an output voltage range of 1.2 V
to 33 V. This voltage regulator is exceptionally easy to use and requires only
two external resistors to set the output voltage. Further, it employs internal
current limiting, thermal shutdown and safe area compensation, making it
essentially blow–out proof.
The LM350 serves a wide variety of applications including local, on card
regulation. This device also makes an especially simple adjustable switching
regulator, a programmable output regulator, or by connecting a fixed resistor
between the adjustment and output, the LM350 can be used as a precision
current regulator.
Guaranteed 3.0 A Output Current
Output Adjustable between 1.2 V and 33 V
Load Regulation Typically 0.1%
Line Regulation Typically 0.005%/V
Internal Thermal Overload Protection
Internal Short Circuit Current Limiting Constant with Temperature
Output Transistor Safe Area Compensation
Floating Operation for High Voltage Applications
Standard 3–lead Transistor Package
Eliminates Stocking Many Fixed Voltages
Simplified Application
* = Cin is required if regulator is located an appreciable distance from power supply filter.
** = CO is not needed for stability, however, it does improve transient response.
Since IAdj is controlled to less than 100
μ
A, the error associated with
this term is negligible in most applications.
