Regulator - L78L33, 3.3 Volt, Positive Voltage Regulator, TO-92
L78L33 3.3V regulator in a TO-92 package. The L78L33 three-terminal 3.3V positive regulator employs internal current limiting and thermal shutdown, making them essentially indestructible. If adequate heat-sink is provided, they can deliver up to 100 mA output current. They are intended as fixed voltage regulators in a wide range of applications including local or oncard regulation for elimination of noise and distribution problems associated with single-point regulation.
In addition, they can be used with power pass elements to make high-current voltage regulators. The L78L series used as Zener diode/resistor combination replacement, offers e improvement along with lower quiescent current and lower noise.
