EMP2133
High-PSRR, Low-Noise, Low-Dropout, 300mA
CMOS Linear Regulator
General Description
The EMP2133 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 EMP2133 is well suited for portable battery-powered
application which requires high efficiency, low noise
and small board space. 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.

Note 1: Absolute Maximum ratings indicate limits beyond which damage may occur. Electrical specifications are not
applicable when the device is operated outside of its rated operating conditions.
Note 2: All voltages are defined and measured with respect to the potential at the ground pin.
Note 3: Maximum Power dissipation for the device is calculated using the following equations:
PD
=
TJ(MAX)
θJA
-
TA
where TJ(MAX) is the maximum junction temperature, TA is the ambient temperature, and θ JA is the
junction-to-ambient thermal resistance. E.g. for the SOT-23-6 packageθJA = 250°C/W, TJ(MAX) = 150°C and using
TA = 25°C, the maximum power dissipation is found to be 500mW. The derating factor (-1/θJA) = -4mW/°C, thus
below 25°C the power dissipation figure can be increased by 4mW per degree, and similarity decreased by this
factor for temperatures above 25°C.
Note 4: Dropout voltage is measured by reducing VIN until VOUT drops 100mV from its nominal value at VIN -VOUT =1V.
Dropout voltage does not apply to the regulator versions with VOUT less than 2.5V.
Note 5: Human body model: 1.5kΩ in series with 100pF.
Note 6: Condition does not apply to input voltages below 2.5V since this is the minimum input operating voltage.
Note 7: Typical Values represent the most likely parametric norm.
Note 8: For different output voltage, the noise can be approximately calculated using the following formula:
Noise = VOUT × 38 (μVRMS )
Note 9: Turn-off time is time measured between the enable input just decreasing below VIL and the output voltage just
decreasing to 10% of its nominal value.
