H7812AA H7812BA
3-TERMINAL POSITIVE VOLTAGE REGULATOR
Description
TO-92 These regulators employ internal current-limiting thermalshutdown, making them essentially indestructible. They deliver 100mA output current. case temperature keep Tc=25°C. They intended fixed voltage regulators wide range applications including local (on-card) regulation elimination noise distribution problems associated with single-point regulation. addition, they used with power pass elements make high-current voltage regulators. H7812_A used Zener diode/resistor combination replacement, offers effective output impedance improvement typically orders magnitude, along with lower quiescent current lower noise.
