EMP8995 - Elite Semiconductor

EMP8995 1A CMOS Linear Regulator

The EMP8995 low-dropout (LDO) CMOS linear regulators feature low dropout voltage (510mV@1A), low quiescent current (120µA), and fast transient response. It guarantees delivery of 1A output current and supports preset 3.3V output voltages. The regulator is stable with small ceramic capacitive loads (2.2µF typical). The EMP8995 is available in miniature SOT-22.
