general description:
   the emp8736 features 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 adjustable output voltages by using two external resistors.
 
based on its low quiescent current consumption and its less than 1μa shutdown mode of logical operation, the emp8736 is ideal for battery-powered applications. the high power supply rejection ratio of the emp8736 holds well for low input voltages typically encountered in battery-operated systems. the regulator is stable with small ceramic capacitive loads (1µf typical). the emp8736 is available in miniature sot-23-5 packages.
