The SC338(A) is an ultra low output voltage dual power supply controller designed to simplify power management for notebook PCs. It is part of Semtech's Smart LDOTM family of products. The SC338(A) has two user adjustable outputs that can be set anywhere between 0.5V and 3.3V (VIN = 12V, anywhere between 0.5V and 1.8V for VIN = 5V) using two external resistors per output.
SC338(A) features for each output include tight output voltage regulation (±2.5% over -40°C to +85°C for SC338, ±1.5% over 0°C to +85°C for SC338A), enable controls, open drain power good signals, under-voltage protection and soft start. The enable pins allow the part to enter a very low power standby mode. Pulling them high enables the outputs. The power good pins are open drain and assert low when the voltage at their respective adjust pins is below 88% (typ.) of nominal. If the voltage at the adjust pin is below 50% (typ.) of nominal, the under voltage protection circuitry will shut down that output. The SC338(A) is available in an MSOP-10 surface mount package.
