MP20049
Ultra-Low Noise, High PSRR
150mA Linear Regulator in 0.8x0.8mm WLCSP
The Future of Analog IC Technology
DESCRIPTION
The MP20049 is an ultra-low noise, low-dropout,
high PSRR linear regulator. Fixed output
voltage options are available between 1.2V to
4.5V with 1% accuracy while operating from a
+2.3V to +6V input. It is designed to deliver up
to 150mA of load current. Dropout voltage is
only 60mV at full load.
The MP20049 uses an internal PMOS as the
pass element, which consumes 50μA supply
current at no load condition and is suitable for
battery-power devices. New innovative design
techniques enable the MP20049 to achieve
ultra-low output voltage noise of only 16µV
RMS
without a noise bypass capacitor.
The MP20049 is designed and optimized to
work with low value, low cost ceramic
capacitors. It typically requires only 1µF of
output capacitance for stability with any load.
The MP20049 features current limit and over
temperature protection and is available in a tiny
4-ball 0.8x0.8mm WLCSP package.

ABSOLUTE MAXIMUM RATINGS

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance
θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX) = (T
J
(MAX)-T
A
)/θ
JA
. Exceeding the maximum allowable power
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) Devices
are
ESD
sensitive.
Handling
precaution
recommended.
4) The device is not guaranteed to function outside of its
operating conditions.
5) Measured on JESD51-7, 4-layer PCB.
