LM78L00 Series 3-Terminal Low Current Positive Voltage Regulators o THREE-TERMINAL LOW CURRENT POSITIVE VOLTAGE REGULATORS The LM78L00 Series of cousins, these regulators feature These devices offer a positive voltage regulators are internal current limiting and thermal substantial performance advantage inexpensive, easy-to-use devices shutdown making them remarkably over the traditional zener diode- suitable for a multitude of rugged. No external components are resistor combination, as output applications that require a regulated required with the LM78L00 devices impedance and quiescent current are supply of up to 100 mA.
