The TLV62130A pulls the PG pin Low, when the device is shut down by EN, UVLO or thermal shutdown.
Connecting PG to Vout through a resistor can be used to discharge Vout in those cases (see Figure 50). The
discharge rate can be adjusted by R3, which is also used to pull up the PG pin in normal operation. For reliability,
keep the maximum current into the PG pin less than 10mA.
