The LP3988-Q1 works with a space-saving 1-µF ceramic capacitor. The LP3988Q1 features an error flag-output that indicates a faulty output condition. The LP3988-Q1 has performance optimized for battery-powered systems to deliver low noise, extremely low dropout voltage, and low quiescent current. Regulator ground current increases only slightly in dropout, further prolonging the battery life. Power-supply rejection is better than 60 dB at low frequencies and starts to roll off at 10 kHz.
