EMP8731 Datasheet | Elite Semiconductor Microelectronics Technology

ESMT Preliminary High-PSRR, Low-Noise, 300m A CMOS Linear Regulator with 3 Types of Output Select General Description The EMP8731 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 300m A output current and supports 3 types of output voltages via ADJ pin.     DSP core power Hand-held instruments Battery-powered systems Portable information appliances Features   300m A guaranteed output current 60d B typical PSRR at 1k Hz 130µV (VOUT=3.0V) RMS output voltage noise (10Hz to 100k Hz)          264m V (VOUT=2.8V) typical dropout at 300m A 60µA typical quiescent current Less than 1µA typical shutdown mode Fast line and load transient response 2.2V to 5.5V input range Auto-discharge during chip disable 60µs typical turn-on time Stable with small ceramic output capacitors Over temperature and over current protection  Based on its low quiescent current consumption and its less than 1µA shutdown mode of logical operation, the EMP8731 is ideal for battery-powered  applications. The high power supply rejection ratio of the EMP8731 holds well for low input voltages typically encountered in battery-operated systems. The regulator is stable with small ceramic capacitive loads (2.2µF typical). The EMP8731 is available in miniature SOT-23-5 packages.
