车规 ET5A0XX
General Description
ET5A0XX series are the fixed output 1A 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, very low dropout, fast start-up and excellent output accuracy.
ET5A0XX series are stable with a 1.0～10μF ceramic output capacitor, uses a precision voltage reference and feedback loop to achieve excellent Regulation and transient response. It can choose the output current between 500mA and 1A by setting the LCON pin to high or low (only some package have this function).
ET5A0XX series are offered SOT23-5, SOT89-5,SOT-223, DNF6(2×2), DNF8(1.2×1.6),HSOP8 packages
