ET533XX数据手册ETEK中文资料规格书

描述 Description

The ET533XX family are the 300mA 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. The ET533XX family are stable with a 1.0μF ceramic output capacitor, uses a precision voltage reference and feedback loop to achieve excellent regulation and transient response. The ET533XX family offered in a small SOT23-5 / SC70-5 / SOT343 / DFN4 / SOT23-3 / SOT89-3 package, which are ideal for small form factor portable equipment.The ET533XX is available in standard fixed output voltages of 1.2V (ET53312), 1.8V (ET53318), 2.5V (ET53325), 2.8 (ET53328), 3.0V (ET53330), 3.3V (ET53333) and custom voltage options (50mV step options between 0.8V and 5.0V are available upon request).
