General Description
The ET537XX 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), low noise, low dropout, low ground current, fast start-up and excellent output accuracy.
The ET537XX 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.
The ET537XX family are offered small DFN4(1×1) package, which is ideal for small form factor portable equipment.
