ET5A8XX General Description

The ET5A8XX series of low-dropout, low-power linear regulators offer up to 1000mA 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 ET5A8XX is stable with a 1μF input and 1µF ceramic output capacitor, and uses a precision voltage reference and feedback loop to achieve accuracy of 1.5%.

It is in small DFN6 (2.0mm ×2.0mm), DFN8 (1.2mm ×1.6mm), SOT23-5 (1.6mm ×2.9mm) package, which is ideal for small form factor portable equipment such as wireless handsets and PDAs.
