PRODUCTION DATA.
Undervoltage lockout (UVLO) prevents the LMR12015/20 from operating until the input voltage exceeds 2.75 V (typical).
The UVLO threshold has approximately 470 mV of hysteresis, so the device operates until VIN drops below 2.28 V (typical). Hysteresis prevents the part from turning off during power up if VIN has finite impedance.
