车规 ET536XXYB
General Description
The ET536XX family are 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) ,ultra low noise, very low dropout ,very low ground current, fast start-up and excellent output accuracy.
The ET536XX family are 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.
Features
