EMP8915 Datasheet | Elite Semiconductor Microelectronics Technology

Description The EMP891X series is a family of CMOS linear regulators, which include EMP8915 and EMP8916, featuring SOT-25, SOT-26 and TDFN-6 packages, the EMP891X series are suitable for portable appliances. EMP products is Ro HS pliant. ultra-high power supply rejection ratio, low output voltage noise, low dropout voltage, low quiescent current and fast transient response. EMP891X Features - - - - - - - - - - Miniature SOT-25, SOT-26 and TDFN-6 packages 150m A guaranteed output current 75d B typical PSRR at 1k Hz (60d B typical at 10KHz) 30µV RMS output voltage noise (10Hz to 100k Hz) 65m V typical dropout at 150m A 106µA typical quiescent current Less than 1μA typical shutdown mode Fast line and load transient response 80µs typical fast turn-on time 2.5V to 5.5V input range Stable with small ceramic output capacitors Over temperature and over current protection ±2% output voltage tolerance ±1% output voltage tolerance for Vout 1.5V guarantees delivery of 150m A output current, and supports preset 1.2V, 1.3V, 1.5V, 1.8V, 2.5V, 2.8V, 2.85V output voltage versions. Based on its low quiescent current consumption and its less than 1μA shutdown mode of logical operation, the EMP891X series are ideal for battery-powered applications. The ground current increases only slightly in dropout, further prolonging the battery life. EMP891X series provide fast turn-on 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 EMP891X holds well for low input voltages typically encountered in battery- operated systems. The regulator is stable with small ceramic capacitive loads (2.2µF typical). - - - - Applications - - - - Wireless handsets PCMCIA cards DSP core power Hand-held instruments Battery-powered systems Portable information appliances Additional features include regulation fault...
