6.3.1 Undervoltage Lockout (UVLO)

The TLV758P uses an undervoltage lockout (UVLO) circuit that disables the output until the input voltage is greater than the rising UVLO voltage (VUVLO). This circuit ensures that the device does not exhibit any unpredictable behavior when the supply voltage is lower than the operational range of the internal circuitry. When VIN is less than VUVLO, the output is connected to ground with a pulldown resistor (RPULLDOWN).
