The LP3986 is a 150mA dual low dropout regulator designed for portable and wireless applications with demanding performance and board space requirements.
The LP3986 is stable with a small 1μF ±30% ceramic output capacitor requiring smallest possible board space.
The LP3986's performance is optimized for battery powered systems to deliver ultra low noise, extremely low dropout voltage and low quiescent current independent of load current. Regulator ground current increases very slightly in dropout, further prolonging the battery life. Optional external bypass capacitor reduces the output noise further without slowing down the load transient response. Fast start-up time is achieved by utilizing a speed-up circuit that actively precharges the bypass capacitor. Power supply rejection is better than 60 dB at low frequencies and 55 dB at 10 kHz. High power supply rejection is maintained at low input voltage levels common to battery operated circuits.
The LP3986 is available in a micro SMD package. Performance is specified for a -40°C to +125°C temperature range.
