Low Noise LDO Regulator
APPLICATION INFORMATION
The SGM2205-12XK3G is a high voltage, low noise and
low dropout LDO and provides 800mA output current.
These features make the device a reliable solution to
solve many challenging problems in the generation of
clean and accurate power supply. The high
performance also makes the SGM2205-12XK3G useful
in a variety of applications. The SGM2205-12XK3G
provides protection functions for output overload, output
short-circuit condition and overheating.
Output Current Limit and Short-Circuit
Protection
When overload events happen, the output current is
internally limited to 1100mA (TYP). When the OUT pin
is shorted to ground, the short-circuit protection will limit
the output current to 230mA (TYP).
Thermal Shutdown
The SGM2205-12XK3G can detect the temperature of
die. When the die temperature exceeds the threshold
value of thermal shutdown, the SGM2205-12XK3G will
be in shutdown state and remain in this state until the
die temperature decreases to +130℃.
Input Capacitor Selection (CIN)
The input decoupling capacitor should be placed as
close as possible to the IN pin to ensure the device
stability. 1μF or larger X7R or X5R ceramic capacitor is
selected to get good dynamic performance.
Power Dissipation (PD)
Thermal protection limits power dissipation in the
SGM2205-12XK3G. When power dissipation on pass
element (PD = (VIN - VOUT) × IOUT) is too much and the
operating junction temperature exceeds +155℃, the
OTP circuit starts the thermal shutdown function and
turns the pass element off.
When VIN is required to provide large current
instantaneously, a large effective input capacitor is
required. Multiple input capacitors can limit the input
tracking inductance. Adding more input capacitors is
available to restrict the ringing and to keep it below the
device absolute maximum ratings.
Therefore, thermal analysis for the chosen application is
important to guarantee reliable performance over all
conditions. To guarantee reliable operation, the junction
temperature of the SGM2205-12XK3G must not exceed
+125℃.
Output Capacitor Selection (COUT
)
The output capacitor should be placed as close as
possible to the OUT pin. 2.2μF or larger X7R or X5R
ceramic capacitor is selected to get good dynamic
performance. The minimum effective capacitance of
The maximum allowable power dissipation depends on
the thermal resistance of the IC package, the PCB
layout, the rate of surrounding airflow, and the
difference between the junction temperature and
ambient temperature. The maximum power dissipation
can be approximated using the following equation:
C
OUT that SGM2205-12XK3G can remain stable is 1μF.
For ceramic capacitor, temperature, DC bias and
package size will change the effective capacitance, so
enough margin of COUT must be considered in design.
Additionally, COUT with larger capacitance and lower
ESR will help increase the high frequency PSRR and
improve the load transient response.
PD(MAX) = (TJ(MAX) - TA)/θJA
(1)
where TJ(MAX) is the maximum junction temperature, TA
is the ambient temperature, and θJA is the junction-
to-ambient thermal resistance.
No-Load Stability
The SGM2205-12XK3G can maintain stability without
output load (except internal voltage divider).
Layout Guidelines
Input Power Supply
To get good PSRR, low output noise and high transient
response performance, the input and output bypass
capacitors must be placed as close as possible to the IN
pin and OUT pin separately. VIN and VOUT had better use
separate ground planes and these ground planes are
single point connected to the GND pin.
The input power supply range is from 3.6V to 36V. VIN
must be larger than (VOUT + VDROP) in application. The
input ceramic capacitor must be placed as close as
possible to the IN pin, this CIN can help improve the
output noise performance of LDO.
