EMP8995-1A CMOS Linear Regulator


EMP8995-1A CMOS Linear Regulator DataSheet

General Description
    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-223 packages.

Applications
  SMPS Post Regulator
  DSP, FPGA and Microprocessor Power
  Wireless Devices
  PC Peripherals
  LCD TV / Monitors
  Portable handheld Devices
