Description

The SC339 is an ultra-low output voltage, linear power supply controller designed to simplify power management for notebook PCs. It is part of Semtech's Smart LDOTM family of products. The SC339 has a user adjustable output that can be set anywhere between 0.5V and 3.3V using two external resistors.

SC339 features include tight output voltage regulation (± 1% over 0°C to +85°C), enable control, open drain power good signal, under-voltage protection and soft-start. The enable pin allows the part to enter a very low power standby mode. Pulling it high enables the output. The power good pin is an open drain and asserts low when the voltage at the adjust pin is below 88% (typ) of nominal. If the voltage at the adjust pin is below 50% (typ) of nominal, the undervoltage protection circuitry will shut down the output. The SC339 is available in a tiny SOT-23 6-pin surface mount package.
