low-battery detector (TPS60120, TPS60122, TPS60124) (continued)
A 100-nF bypass capacitor should be connected in parallel to R2 if large line transients are expected. These
voltage drops can inadvertently trigger the low-battery comparator and produce a wrong low-battery warning
signal at the LBO terminal.
power-good detector (TPS60121, TPS60123, TPS60125)
The PG terminal is an open-drain output that is pulled low when the output is out of regulation. When the output
voltage rises to about 90% of its nominal voltage, the power-good output is released. PG is high impedance
when the device is disabled. A pullup resistor must be connected between PG and OUT. The pullup resistor
should be in the 100-k
to 1-M range. If the power-good function is not used, then PG should remain
unconnected.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
