Implementing this device at point- of-source removes the complexity of single point regulation methods + reduces noise. In replacement of a Zener diode/resistor combination, the device improves output impedance by x2 order of magnitude and delivers lower bias current with lower noise. The 79L12 can also be used with power-pass elements to make high-current voltage regulators.

-VOUT 79L12 CI 0.33µf CO 0.1µf -VIN CI is required if the regulator is located an appreciable distance from power supply filter. CO is not required for stability; however it does improve transient response. For optimum stability and transient response locate CI CO as close as possible to the regulator. 940µm (37.00 mils) 1000µm (39.37 mils) + + (0,0) 1 2
