10 / 21 page Application information L79xxC 10/21 6 Application information 1. To specify an output voltage, substitute voltage value for "XX". 2. Required for stability. For value given, capacitor must be solid tantalum. If aluminium electrolytic are used, at least ten times value should be selected. C1 is required if regulator is located an appreciable distance from power supply filter. 3. To improve transient response. If large capacitors are used, a high current diode from input to output (1N4001 or similar) should be introduced to protect the device from momentary input short circuit. (*) Against potential latch-up problems. Figure 4. Fixed output regulator Figure 5. Split power supply (± 15 V - 1 A) |
