Overview
ESMT/EMP CMOS Linear Regulator General Description The EMP2033 series is a family of dual-channel CMOS linear regulators featuring ultra-high power supply rejection ratio (PSRR), low output voltage noise, low dropout voltage, low quiescent current and fast transient response.
It guarantees delivery of 300mA output current per regulator, and supports preset output voltages ranging from 1.
2V to 3.
3V with 0.
1V increment (except for 1.
85V and 2.
85V).
The EMP2033 is well suited for portable battery-powered application which requires high efficiency, low noise and small board space.
With 150mV low dropout voltage at 300mA output current, EMP2033 sustains high PSRR at very low input voltage which is common in battery-powered application.
The EMP2033 also features 120µVRMS 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 EMP2033 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 EMP2033 is available in miniature 6-pin SOT-23-6, 6-pin FBP and TDFN (2x2) packages.
