General Description
The CE53L8XXZB of low-dropout (LDO), low-power linear regulators offer up to 400mA with PMOS pass transistor. The device offers low noise, high PSRR, low quiescent current and very good line/load transients, suitable for RF applications and analog circuits.
The CE53L8XXZB is stable with a 1μF input and 1uF ceramic output capacitor, and uses a precision voltage reference and feedback loop to achieve accuracy of 1.5%.
It is in a small WLCSP4(0.635mm×0.635mm) package, which is ideal for small form factor portable equipment such as wireless handsets and PDAs.
