L7800 SERIES POSITIVE VOLTAGE REGULATORS OUTPUT CURRENT TO 1.5A OUTPUT VOLTAGES OF 5; 5.2; 6; 8; 8.5; 9; 12; 15; 18; 24V THERMAL OVERLOAD PROTECTION SHORT CIRCUIT PROTECTION OUTPUT TRANSITION SOA PROTECTION DESCRIPTION The L7800 series of three-terminal positive regulators is available in TO-220, TO-220FP, TO-3 and D2PAK packages and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.

Figure 31 : Adjustable Output Voltage with Temperature Compensation R2 VO = VXX (1+ ) + V BE R1 NOTE: Q2 is connected as a diode in order to compensate the variation of the Q1 VBE with the temperature. C allows a slow rise time of the VO. Figure 32 : Light Controllers (VOmin = VXX + VBE) VO falls when the light goes up 22/29 VO rises when the light goes up L7800 SERIES Figure 33 : Protection against Input Short-Circuit with High Capacitance Loads Application with high capacitance loads and an output voltage greater than 6 volts need an external diode (see fig. 33) 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. 23/29 L7800 SERIES TO-3 MECHANICAL DATA mm. DIM. MIN.
