1 Three-Terminal Low Current Positive Voltage Regulator Features Three-Terminal Regulators Maximum Input Voltage : 30V Output Voltages of 5V, 12V Output Current Up to 100m No External Components Internal Thermal Overload Protection Internal Short-Circuit Limiting Output Voltage Offered in 4% Tolerance SOP-8, SOT-89, and TO-92 Packages Lead Free and Green Devices vailable (RoHS Compliant) pplications General Description These series of fixed-voltage monolithic integrated-circuit voltage regulators are designed for a wide range of applications. These applications include on-card 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 highcurrent voltage regulators. Each of these regulators can deliver up to 100m of output current. The internal limiting and thermal shutdown features of these regulators make them essentially immune to overload. When used as a replacement for a Zener diode-resistor combination, an effective improvement in output impedance can be obtained together with lower-bias current.

TO-92 SOT-89 NME FUNCTION V OUT Output Voltage Output Pin. 2,3,6,7 2 2 GND Ground. common ground is required between the input and the output voltage. 4,5 - - NC No Internal Connection V IN Power input pin of the device. The maximum Input Voltage can be 30V. It should be bypassed with a 0.33µF (minimum) capacitor to the GND. Typical pplication Circuit V IN PL78L05/12 V OUT C IN = 0.33µF C OUT = 0.1µF Note a : common ground is required between the input and the output voltage. The input voltage must remain typically 2V above the output voltage even during the low point on the input ripple voltage. b : C IN is required if regulator is located an appreciable distance from power supply filter. c : C OUT is not needed for stability; however, it improves transient response. 7

8 pplication Information The PL78L05/12, series of fixed voltage regulators, are designed with thermal overload protection that shuts down the circuit when subjected to an excessive power overload condition. In addition, the PL78L05/12 have the function of internal short circuit protection to limit the maximum current the circuit will pass. In many low current applications, compensation capacitors are not required. However, it is recommended that the regulator input will be bypassed with a capacitor if the regulator connects to the power supply filter with long wire lengths, or if the output load capacitance is large. The input bypass capacitor should be selected to provide good high-frequency characteristics to insure stable operation under all load conditions. If the value of the capacitor is greater than 0.33µF, the capacitor with tantalum or mylar, or other capacitor having low internal impedance at high frequencies should be chosen. The bypass capacitor should be mounted with the shortest possible leads directly across the regulators input terminals. Good construction techniques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense lead. Bypassing the output is also recommended. For example, a 100m current source would require R to be a 50Ω, 1/2W resistor and the output voltage compliance would be the input voltage less 7V. +20V PL78L05 +VO 0.33µF 0.33µF 20V MC K 10K MPS VO MPSU55 Figure 2. ±15V Tracking Voltage Regulator +VI PL78LXX +VO 0.33µF 0.1µF -VI PL79LXX 0.33µF 0.1µF Input PL78L05 -VO 0.33µF lo R Constant Current to Grounded Load Figure 3.
