Datasheet Summary
General Description
The AMS4123 bines a 3A Step-Down converter with a 1A LDO in a single SO-8 exposed paddle package. Both the LDO and Step-Down converter are low ESR, ceramic capacitor output, stable. The Step-Down converter is internally pensated with internal soft-start to minimize the number of external ponents. An Enable pin provides built-in externally programmable power-up sequencing. The Step-Down converter enable threshold is 2.0V and the LDO enable threshold is 2.5V. It also has hiccup current limit and thermal protection. Thermal protection shuts down both the Step-Down converter and LDO when the die temperature exceeds 135°C. Both regulators are adjustable using a 0.6V...
