8.2.2 Detailed Design Procedure

The minimum application circuit requires the LP3470 Power-On Reset Circuit IC and a pullup resistor connecting

the reset pin to VCC. The reset delay can be programmed with an additional capacitor connected from the SRT

pin to GND. See Reset Time-Out Period and Pullup Resistor Selection for information on choosing specific

values for components.

8.2.3 Application Curves

Two capacitor values for CD (0.1 µF and 1 µF) are used as examples to show the programmability of the output

time delay as shown in Figure 11 and Figure 12.
