EMP2033
Dual, High-PSRR, Low-Noise, Low-Dropout, 300mA
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.
