车规 ET5C108
General Description
The ET5C108 is a CMOS-based very low dropout voltage regulator, offering 3A with NMOS pass transistor and a separate bias supply voltage (VBIAS). The device provides very stable, accurate output voltage with high ripple rejection and excellent full load transient performance. The ET5C108 consist of an accurate 0.8V internal voltage-reference, an error amplifier, an under-voltage lock-out (UVLO) block, an output current limit circuit and a thermal-shutdown circuit.
The ET5C108 can set the output voltage through external resistor divider with FB pin. With the SS pin, user can fulfill the soft-start function through the external capacitor. A Power Good pin (PG) is also available. The ET5C108 is offered in DFN10(3mm×3mm) package.
