Design Requirements

For this design example, use the values listed in Table 3 as the design parameters:

Table 3. Design Parameters

DESIGN PARAMETER EXAMPLE VALUE
Input Voltage (VIN ) 5 V
Load Current / Resistance (RL) 1 kΩ
Load Capacitance (CL) 10 µF
Maximum Inrush Current (IINRUSH) 100 mA

Although the load capacitance is 10 µF, this is assumed to be at the end of a cable or closer to the load. An 18nF capacitance close to the output of the device is recommended for optimal performance during short circuit conditions.
