TLV757P
Every spec below is cited to the manufacturer datasheet. Pick your exact ordering code, compare the closest alternatives, then ask the assistant what it means for your design.
What the TLV757P family does
The TLV757P is a 1-A, low quiescent current, low dropout regulator available in fixed output voltages from 0.6 V to 5 V in 50-mV steps. It operates with an input voltage range of 1.45 V to 5.5 V and features a typical quiescent current of 25 µA. The device maintains a maximum dropout of 425 mV at 1 A and provides 1% output accuracy. It includes built-in soft-start, foldback current limit, and active output discharge to ensure safe operation. This regulator is typically used in portable battery-powered equipment, set-top boxes, gaming consoles, and ultrabooks where small size and low power consumption are critical.
