Feature Description (continued)

7.3.5 Undervoltage Lockout (UVLO)

The TPS799xx-Q1 utilizes a UVLO circuit to keep the output shut off until internal circuitry is operating properly.

The UVLO circuit has a deglitch feature so that it typically ignores undershoot transients on the input if they are

less than 50-

μs duration.

7.4 Device Functional Modes

Driving EN over 1.2 V turns on the regulator. Driving EN below 0.4 V puts the regulator into shutdown mode,

thus reducing the operating current to 150 nA, nominal.
