ET533XXAM中文资料High PSRR Low Noise 300mA LDO数据手册ETEK规格书

描述 Description

The ET533XXAM is the high performance 300mA 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 ET533XXAM 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.
