The 78L23 is a three terminal voltage regulator in a TO-92 package suitable for numerous applications requiring up to 100mA. This device features thermal shutdown and current limiting making the 78L24 remarkably rugged. In most applications, no external components are required for operation. The 78L24 is useful for on-card regulation or any other application where a regulated negative voltage at a modest current level is needed. This device offers a substantial advantage over the common resistor/zener diode approach.
