OUTPUT OVER-VOLTAGE PROTECTION
The LMR10530 has a built in output over-voltage comparator that compares the FB pin voltage to a threshold
voltage that is 15% higher than the internal reference V
REF
. Once the FB pin voltage exceeds this threshold level
(typically 0.69V), the internal PMOS power switch is turned off, which allows the output voltage to decrease
towards regulation.
UNDER-VOLTAGE LOCKOUT
Under-voltage lockout (UVLO) prevents the LMR10530 from operating until the input voltage exceeds 2.70V
(typical). The UVLO threshold has approximately 350mV of hysteresis, so the part will operate until V
IN
drops
below 2.35V (typical). Hysteresis prevents the part from turning off during power up if V
IN
is non-monotonic.
