SNVS852D June 2012 – August 2018 LMZ20502
The circuit in Figure 17 highlights the use of the features of the LMZ20502. The PG output is open drain, and requires a pull-up resistor to a logic supply that is commensurate with the system logic voltage levels. If a reset function is not needed, the PG pin should be left open. The EN and MODE inputs are digital inputs, requiring only simple logic levels for proper operation. If the system does not need to control these features, the inputs should be connected to either VIN or GND, as appropriate. Please see Feature Description for details.
