概要

The ET538XXYB 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 ET538XXYB 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 DFN4(1×1)/WLCSP4(0.635mm×0.635mm) package, which is ideal for small form factor portable equipment such as wireless handsets and PDAs.
