General Description
ET552XXY1B is output 500mA LDO with auto discharge function, It uses an advanced CMOS process and a PMOSFET pass device to achieve high power supply rejection ratio (PSRR) , low noise, low dropout ,low ground current, fast start-up and excellent output accuracy in low input condition. ET55233Y1B is stable with a 1.0μF ceramic output capacitor, uses a precision voltage reference and feedback loop to achieve excellent Regulation and transient response. ET55233YB is offered in a small DFN4(1×1) package, which is ideal for small form factor portable equipment .
