GENERAL DESCRIPTION
With 130mV low dropout voltage at 300mA output current, EMP2133 sustains high PSRR at very low input voltage which is common in battery-powered application. The EMP2133 also features 110µVRMS low output voltage noise without the presence of a noise bypass capacitor, which fits the application where noise and board space are both concerned. Each regulator in the EMP2133 can be turned off independently, further prolonging the battery life. Internally build-in thermal protection and over-current protection provide additional safety for the end use. The EMP2133 is available in miniature SOT-23-6 and TSOP-6 package.
