Equivalent Circuit Block Diagram Sample Application Circuit td = 100 x Cd (mF) [ms] NOTES: 1. When Cd ≥ 10 mF, the capacitor may not discharge completely, causing td to be made shorter than a set value. In this case, connect high−speed diode (DS442) across pin 2 (anode side) and pin 5 (cathode side) 2. Connecting a pull−up resistor to the reset output externally allows sink current up to 4 mA to flow. Figure 4. Sample Application Circuit www.onsemi.com 3 L78LR05D−MA−E Reset Operation Figure 5.
