车规 ET5A5ADJZB
General Description
The ET5A5ADJZB is CMOS-based low-dropout, low-power linear regulators, offering 1500mA with NMOS pass transistor and a separate bias supply voltage(VBIAS). The device provides very stable, accurate output voltage with low noise, high ripple rejection and low supply current suitable for space constrained, noise sensitive application. ET5A5ADJZB consists of an accurate voltage-reference block, an error amplifier, a thermal-shutdown circuit, and a current limit circuit.
