MC1560 ¢ MC1561 MC1460 e MC1461 GENERAL INFORMATION Latch-up of these and other regulators can occur if: 1. There are plus and minus voltages available 2. A load exists between Vo* and Vo™ (This “common load" may be something inconspicuous —e.g. an operational amplifier. Nearly everyone who uses + and ~ voltages will have a common load from V* to V7), 3. Vin® and Vjin* are not applied at the same time. The above conditions result in one of the two outputs becoming reverse-biased which prevents the regulator from turning “on”. Latch-up can be prevented by the circuit configurations shown in Figure 29 and 30. FIGURE 29 Vint ig 1 Rs Vo*
