Dropout voltage for the TLV743P is not valid at room temperature. The device engages undervoltage lockout (VIN < UVLOFALL) before

the dropout condition is met.

6.5 Electrical Characteristics

at operating temperature range (TJ = –40°C to +125°C), VIN = VOUT(nom) + 0.5 V or 2 V (whichever is greater), IOUT = 1 mA,

VEN = VIN, and CIN = COUT = 1 µF (unless otherwise noted). All typical values at TJ = 25°C.
