Description
General part information
LP3985 Series
The LP3985 is designed for portable and wireless applications with demanding performance and space requirements. LP3985 performance is optimized for battery-powered systems to deliver ultra low noise, extremely low dropout voltage, and low quiescent current. Regulator ground current increases only slightly in dropout, further prolonging the battery life.
The LP3985 is stable with a small 1-µF ±30% ceramic or high-quality tantalum output capacitor. The DSBGA requires the smallest possible PC board area – the total application circuit area can be less than 2 mm × 2.5 mm, a fraction of a 1206 case size.
An optional external bypass capacitor reduces the output noise without slowing down the load transient response. Fast startup time is achieved by utilizing an internal power-on circuit that actively pre-charges the bypass capacitor.
