The EMP893X series is a family of CMOS linear regulators. It is consisted of EMP8935, EMP8936 and EMP8938, featuring ultra-high power supply rejection ratio, low output voltage noise, low dropout voltage, low quiescent current and fast transient response. It guarantees delivery of 300mA output current, and supports preset (1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 2.85V, 3.0V, 3.3V) as well as adjustable (1.2V to 5.0V) output voltage versions.
Based on its low quiescent current consumption and its less than 1μA shutdown mode of logical operation, the EMP893X is ideal for battery-powered applications. It provides fast turn-on and start-up time by using dedicated circuitry to pre-charge an optional external bypass capacitor. This bypass capacitor is used to reduce the output voltage noise without adversely affecting the load transient response. The high power supply rejection ratio of the EMP893X holds well for low input voltages typically encountered in battery- operated systems. The regulator is stable with small ceramic capacitive loads (2.2μF typical).
Additional features include regulation fault detection, bandgap voltage reference, constant current limiting and thermal overload protection. Available in miniature 8-pin MSOP and 6-pin DFN (2x2) packages, the EMP893X is pin and package compatible with the MAX8860 and the LP3982. A 5-pin SOT-25 package option is also offered to provide additional flexibility for
