L78 Positive voltage regulator ICs Datasheet - production data Description The L78 series of three-terminal positive regulators is available in TO-220, TO-220FP, DPAK and DPAK packages and several fixed output voltages, making it useful in a wide range of applications. TO-220 DPAK These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type embeds internal current limiting, thermal shutdown and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents. TO-220FP DPAK Features * Output current up to 1.5 A * Output voltages of 5; 6; 8; 8.5; 9; 12; 15; 18; 24 V * Thermal overload protection * Short circuit protection * Output transition SOA protection * 2 % output voltage tolerance (A version) * Guaranteed in extended temperature range (A version) February 2016 This is information on a product in full production.

Minimum load current for regulation is 5 mA. 22/59 DocID2143 Rev 33 L78 Application information 6 Application information 6.1 Design consideration The L78 Series of fixed voltage regulators are designed with thermal overload protection that shuts down the circuit when subjected to an excessive power overload condition, internal short-circuit protection that limits the maximum current the circuit will pass, and output transistor safe-area compensation that reduces the output short-circuit current as the voltage across the pass transistor is increased. In many low current applications, compensation capacitors are not required. However, it is recommended that the regulator input be bypassed with capacitor if the regulator is connected to the power supply filter with long lengths, or if the output load capacitance is large. An input bypass capacitor should be selected to provide good high frequency characteristics to insure stable operation under all load conditions. A 0.33 F or larger tantalum, 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. Normally good construction techniques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense lead. The addition of an operational amplifier allows adjustment to higher or intermediate values while retaining regulation characteristics. The minimum voltage obtained with the arrangement is 2 V greater than the regulator voltage. The circuit of Figure 13 can be modified to provide supply protection against short circuit by adding a short circuit sense resistor, RSC, and an additional PNP transistor. The current sensing PNP must be able to handle the short circuit current of the three terminal regulator Therefore a four ampere plastic power transistor is specified. Figure 8. Fixed output regulator 1. Although no output capacitor is need for stability, it does improve transient response. 2. Required if regulator is located an appreciable distance from power supply filter.

Protection against input short-circuit with high capacitance loads Note: 32/59 Application with high capacitance loads and an output voltage greater than 6 volts need an external diode (see Figure 22 on page 29) to protect the device against input short circuit. In this case the input voltage falls rapidly while the output voltage decrease slowly. The capacitance discharges by means of the base-emitter junction of the series pass transistor in the regulator. If the energy is sufficiently high, the transistor may be destroyed. The external diode by-passes the current from the IC to ground.
