3 Terminal Adjustable Positive Voltage Regulator
1.2V to 33V, 3A
Description:
The NTE1929 is an adjustable 3–terminal positive voltage regulator in a TO220 type package capable
of supplying in excess of 3A over an output voltage range of 1.2V to 33V. This device employes inter-
nal current limiting, thermal shutdown, and safe area compensation making the it essentially blow–out
proof.
The NTE1929 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,
and can also be used as a precision current regulator.
Features:
D Guaranteed 3A Output Current
D Output Adjustable Between 1.2V and 33V
D Load Regulation Typically 0.1%
D Line Regulation Typically 0.005%/V
D Internal Thermal Overload Protection
D Internal Short–Circuit Current Limiting Constant with Temperature
D Floating Operation for High Voltage Applications
D Standard 3–Lead TO220 Type Transistor Package
D Eliminates Stocking many Fixed Voltages

Note 1. Thermal Resistance evaluated measuring the hottest temperature on the die using an in-
frared scanner. This method of evaluation yields very accurate thermal resistance values
which are conservativeompared to other measurement techniques.
Note 2. The average die temperature is used to derive the value of thermal resistance junction to
case (average).

Note 3. Load and line regulation are specified at constant junction temperature. Changes in VO due
to heating effects must be taken into account separately. Pulse testing with low duty cycle
is used.
Note 4. CAdj, when used, is connected between the adjustment pin and GND.
Note 5. Since LongTerm Stability cannot be measured on each device before shipment, this speci-
fication is an engineering estimate of average stability from lot to lot.
