EMP8734 Datasheet | Elite Semiconductor Microelectronics Technology

ESMT/EMP CMOS Linear Regulator General Description The EMP8734 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 preset output voltages ranging from 0.8V to 4.5V with 0.05V increment. Based on its low quiescent current consumption and its less than 1μA shutdown mode of logical operation, the EMP8734 is ideal for battery-powered applications. The high power supply rejection ratio of the EMP8734 holds well for low input voltages typically encountered in battery-operated systems. The regulator is stable with small ceramic capacitive loads (1µF typical). The EMP8734 is Available in miniature TDFN-6 SOT-23-5 SOT-353(SC-70-5 ), SOT-343 and packages. - - - - - - - - - - - - - EMP8734 Fast Ultra High-PSRR, Low-Noise, 300m A 300m A guaranteed output current 62d B typical PSRR at 1k Hz 110µV RMS output voltage noise (10Hz to 100k Hz) 290m V typical dropout at 300m A 57µA 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 80µs typical turn-on time Stable with small ceramic output capacitors Over temperature and over current protection ±2% output voltage tolerance Applications - - - - - - Wireless handsets PCMCIA cards DSP core power Hand-held instruments Battery-powered systems Portable information appliances Features Typical Application - Use 2.2μF for VOUT < 1.2V Elite Semiconductor Memory Technology Inc./Elite Micro Power Inc.
