RT9172  
3A Fixed Output Voltage LDO Regulator  
General Description  
Features  
Low Dropout Voltage  
The RT9172 series of low-dropout linear regulators operate  
from a +2.25V to +6.0V input supply.Awide range of preset  
output voltage options is available. These low dropout linear  
regulators respond very fast to step changes in load, which  
are suitable for low voltage microprocessor applications.  
The RT9172 uses an internal PMOS as the pass device,  
which does not cause extra GND current in heavy load  
and dropout condition. The shutdown mode of low operation  
current makes the IC suitable for power-saving systems.  
The other features include current limiting and over  
temperature protection.  
Low Ground Pin Current  
Load Regulation of 0.4% at 3A  
0.5mA Quiescent Current in Shutdown Mode  
Guaranteed Output Current of 3A DC

Application Information  
Sense Pin  
Capacitor Selection  
In applications where the regulator output is not very close  
to the load, RT9172 can provide better remote load  
regulation using the SENSE pin. Figure 2. and Figure 3.  
depict the advantage of the SENSE option. RT9172  
regulates the voltage at the output pin. Hence, the voltage  
at the remote load will be the regulator output voltage  
minus the drop across the trace resistance. For example,  
in the case of a 3.3V output, if the trace resistance is  
100mΩ, the voltage at the remote load will be 3V with 3A  
of load current, ILOAD. The RT9172 regulates the voltage  
at the sense pin. Connecting the sense pin to the remote  
load will provide regulation at the remote load, as shown  
in Figure 2. and Figure 3.  
An output capacitor as part of the device frequency  
compensation to maintain stability and improve  
transient response.  
Proper capacitor selection is important to ensure proper  
operation. When the output capacitor is 10μF or greater,  
the output capacitor should have an ESR less than 2Ω.  
This will improve transient response as well as promote  
stability.  
Ultra-low-ESR capacitor (<100mΩ), such as ceramic  
chip capacitors, may promote instability. These very  
low ESR levels may cause an oscillation and/or  
underdamped transient response. A low-ESR solid  
tantalum capacitor works extremely well and provides  
good transient response and stability over temperature.  
Aluminum electrolytics can also be used, as long as  
the ESR of the capacitor is <2Ω. The value of the output  
capacitor can be increased without limit. Higher  
capacitor values help to improve transient response  
and ripple rejection and reduce output noise.  
Chip Enable Operation  
A CMOS logic level signal at the chip enable (EN) pin will  
turn-off the regulator. Pin EN must be actively terminated  
through a 10kΩ pull-up resistor for a proper operation. If  
this pin is driven from a source that actively pulls high  
and low (such as a CMOS rail to rail comparator), the  
pull-up resistor is not required. This pin must be tied to  
VIN if not used.  
The RT9172 requires a minimum input capacitance of  
1μF between the input and ground pins to prevent any  
impedance interactions with the supply. The RT9172  
requires a minimum of 10μF (tantalum, or electrolytic)  
capacitance between the output and ground pins for  
proper operation. Please note that the part must be  
paralleled with the least a 100μF electrolytic capacitor  
when using a 10μF (or greater) ceramic type as the  
output capacitor to prevent the output oscillating.  
Dropout Voltage  
The dropout voltage of a regulator is defined as the minimum  
input-to-output differential required to stay within 2% of  
the output voltage. The RT9172 uses an internal MOSFET  
with an RDS(ON) 160mΩ. For CMOS LDOs, the dropout  
voltage is the product of the load current and the RDS(ON)  
of the internal MOSFET.  
Error Operation (FLG)  
Maximum Output Current Capability  
The RT9172 produces a logic low signal at the FLG pin  
when the output drops out of regulation due to low input  
voltage, current limiting, or thermal limiting.  
RT9172 can deliver a continuous current of 1.5Aover the  
full operating temperature range.Aheatsink may be required  
depending on the maximum power dissipation and  
maximum ambient temperature of the application. Under  
all possible conditions, the junction temperature must be  
within the range specified under operating conditions. The  
total power dissipation of the device is given by : PD = (VIN  
- VOUT) IOUT+ (VIN) IGND  
The internal error FLG comparator has an open drain  
output stage. Hence, the FLG pin should be pulled high  
through a pull up resistor.  
where IGND is the operating ground current of the device  
(specified under Electrical Characteristics).
