NTE1929 Terminal Adjustable Positive Voltage Regulator 1.2V 33V,
Description: NTE1929 adjustable 3-terminal positive voltage regulator TO220 type package capable supplying excess over output voltage range 1.2V 33V. This device employes internal current limiting, thermal shutdown, safe area compensation making essentially blow-out proof. NTE1929 serves wide variety applications including local, card regulation. This device also makes especially simple adjustable switching regulator, programmable output regulator, also used precision current regulator. Features: Guaranteed Output Current Output Adjustable Between 1.2V Load Regulation Typically 0.1% Line Regulation Typically 0.005%/V Internal Thermal Overload Protection Internal Short-Circuit Current Limiting Constant with Temperature Floating Operation High Voltage Applications Standard 3-Lead TO220 Type Transistor Package Eliminates Stocking many Fixed Voltages Absolute Maximum Ratings: Input-Output Voltage Differential, VI-VO Power Dissipation, Internally Limited Operating Junction Temperature Range, +125°C Storage Temperature Range, Tstg -65° +150°C Lead Temperature (During Soldering, 10sec), +300°C Thermal Resistance, Junction-to-Case, RthJC Peak (Note 2.3°C/W Average (Note 1.5°C/W Note Thermal Resistance evaluated measuring hottest temperature using infrared scanner.
