ET559XX

General Description

The ET559XX is the high performance 500mA LDO with auto discharge function, it uses an advanced CMOS process and a PMOSFET pass device to achieve very high-power supply rejection ratio (PSRR), very low noise, very low dropout, very low ground current, fast start-up and excellent output accuracy. The ET559XX is stable with a 1.0μF ceramic input and output capacitor, uses a precision voltage reference and feedback loop to achieve high excellent Regulation and transient response. The ET559XX is offered small DFN4(1×1) and SOT23-5 package, which is ideal for small form factor portable equipment.
