General Description
The CE53L3XXQ is 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), very low noise, very low dropout, very low ground current, fast start-up and excellent output accuracy.
The CE53L3XXQ is 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.
CE53L3XXQ operates over an ambient temperature range of -40°C to 125°C.
