Typical Characteristics (continued)
Characteristics in this section are based on using the applicable Detailed Application Circuit — 2.
Output Under-voltage Response — Normal Operation
VIN = 12V, VOUT = 1.5V, IOUT = 0A, VLDO = VDD = ENL = 3.3V, floating EN/PSV
Output Over-current Response — Normal Operation
VIN = 12V, VOUT = 1.5V, VLDO = VDD = ENL = 3.3V, EN/PSV= floating; IOUT ramped to trip point
