600mA High PSRR Low Noise LDO
General Description
Applications
The EM1106 performs ultra low drop voltage,
high power supply rejection ratio (PSRR), fast
response, low noise linear regulator, and designed
to continuously deliver up to 600mA output current.
The EM1106 has wide adjustable output voltage
range and high output accuracy to 2%.
No by-pass capacitor is needed for this device
and only 1uF ceramic capacitor is required for
stability in any loading conditions. It reduces the
amount of board space necessary for power
applications.

EM1106
Functional Description
For recommended specification of EM1106, the
max junction temperature is 125 degree C. The θJA
of SOT23-5 is 250°C/W on the standard JEDEC 51-3
thermal test board. The max power dissipation (at
25°C ambient) can be calculated as below:
Enable Function
EM1106 is enabled if the voltage of the EN pin is
greater than 1.4V. If the voltage of the EN pin is
less than 0.38V, the IC will be disabled.
PD(max at 25°C)=(125°C – 25°C) / (250°C/W) = 0.4W
POR – Power ON Reset
To let EM1106 start to operation, input voltage
must be higher than its POR voltage even when EN
voltage is pulled higher than enable high voltage.
Typical POR voltage is 2.1V.
The θJA of DFN2X2 is 165°C/W on the standard
JEDEC 51-3 thermal test board. The max power
dissipation (at 25°C ambient) can be calculated as
below:
VOUT Voltage Adjustment
PD(max at 25°C)=(125°C – 25°C) / (165°C/W) = 0.6W
The VOUT voltage of EM1106 can be adjusted by
external voltage divider. Refer to typical
application circuit, VOUT voltage is calculated by
the following equation,
R
VOUT = (1 + 1 )× 0.8V
R2
Over Current Limit Function
EM1106 features over current limiting function
which can limit its output current to 800mA.
Input and Output Capacitor Selection
For VIN pin, 1uF or larger ceramic capacitor is
required to provide bypass path in transient
current demand. VOUT pin is also recommended to
have 1uF or larger ceramic capacitor to be stable
and reduce the VOUT voltage dip when fast loading
transient is happened.
Power Dissipation
The max power depends on some conditions,
including of thermal impedance, PCB layout,
airflow, and so on. The max power dissipation can
be calculated by the formula as below
PD(max)=(TJ(max)-TA) / θJA
TJ(max) is the max junction temperature; θJA is the
thermal impedance from junction to ambient. The
thermal impedance θJA of SOT23-5 / DFN2X2 is
package design and PCB design dependent.
