TC1174  
300mA CMOS LDO with Shutdown and VREF Bypass  
Features  
General Description  
• Extremely Low Supply Current (50A, Typ.)  
• Very Low Dropout Voltage  
The TC1174 is an adjustable output CMOS low dropout  
regulator. Total supply current is typically 50A at full  
load (20 to 60 times lower than in bipolar regulators).  
• 300mA Output Current  
TC1174 key features include ultra low noise operation  
(plus optional Bypass input); very low dropout voltage  
(typically 270mV at full load) and internal feed-forward  
compensation for fast response to step changes in  
load. Supply current is reduced to 0.05A (typical) and  
VOUT falls to zero when the shutdown input is low.  
• Adjustable Output Voltages  
• Power Saving Shutdown Mode  
• Bypass Input for Ultra Quiet Operation  
• Over Current and Over Temperature Protection  
• Space-Saving MSOP Package Option  
The TC1174 incorporates both over temperature and  
over current protection. The TC1174 is stable with an  
output capacitor of only 1F and has a maximum  
output current of 300mA.

2: Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range  
from 0.1mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal  
regulation specification.  
3: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at a  
1V differential.  
4: Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or  
line regulation effects. Specifications are for a current pulse equal to ILMAX at VIN = 6V for T = 10 msec.  
5: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the  
thermal resistance from junction-to-air (i.e., TA, TJ, JA). Exceeding the maximum allowable power dissipation causes the device to initiate  
thermal shutdown. Please see Section 4.0 Thermal Considerations for more details.  
6: The minimum VIN has to justify the conditions: VIN VR + VDROPOUT and VIN 2.7V for IL = 0.1mA to IOUTMAX

DETAILED DESCRIPTION  
A 470pF capacitor connected from the Bypass input to  
ground reduces noise present on the internal  
reference, which in turn significantly reduces output  
noise. If output noise is not a concern, this input may be  
left unconnected. Larger capacitor values may be  
used, but results in a longer time period to rated output  
voltage when power is initially applied.  
The TC1174 is an adjustable low drop-out regulator.  
Unlike bipolar regulators, the TC1174’s supply current  
does not increase with load current. In addition, VOUT  
remains stable and within regulation over the entire  
0mA to IOUTMAX operating load current range, (an  
important consideration in RTC and CMOS RAM  
battery back-up applications).  
Figure 3-1 shows a typical application circuit. The  
regulator is enabled any time the shutdown input  
(SHDN) is at or above VIH, and shutdown (disabled)  
when SHDN is at or below VIL. SHDN may be  
controlled by a CMOS logic gate, or I/O port of a  
microcontroller. If the SHDN input is not required, it  
should be connected directly to the input supply. While  
in shutdown, supply current decreases to 0.05A  
(typical), VOUT falls to zero.  
3.2  
Output Capacitor  
A 1F (min) capacitor from VOUT to ground is required.  
The output capacitor should have an effective series  
resistance greater than 0.1and less than 5.0. A 1F  
capacitor should be connected from VIN to GND if there  
is more than 10 inches of wire between the regulator  
and the AC filter capacitor, or if a battery is used as the  
power source. Aluminum electrolytic or tantalum  
capacitor types can be used. (Since many aluminum  
electrolytic capacitors freeze at approximately -30°C,  
solid tantalums are recommended for applications  
operating below -25°C.) When operating from sources  
other than batteries, supply-noise rejection and  
transient response can be improved by increasing the  
value of the input and output capacitors and employing  
passive filtering techniques.

THERMAL CONSIDERATIONS  
Thermal Shutdown  
)
JA  
Integrated thermal protection circuitry shuts the  
regulator off when die temperature exceeds 150°C.  
The regulator remains off until the die temperature  
drops to approximately 140°C.  
Where all terms are previously defined.  
Equation 4-1 can be used in conjunction with Equation  
4-2 to ensure regulator thermal operation is within  
limits. For example:  
4.2  
Power Dissipation  
Given:  
The amount of power the regulator dissipates is  
primarily a function of input and output voltage, and  
output current. The following equation is used to  
calculate worst case actual power dissipation:  
VINMAX  
= 3.0V + 10%  
VOUTMIN = 2.7V – 0.5%  
ILOADMAX = 250mA  
TJMAX  
TAMAX  
= 125°C  
= 55°C  
EQUATION 4-1:  
8-Pin MSOP Package  
PD (VINMAX – VOUTMIN)ILOADMAX  
Find: 1. Actual power dissipation  
2. Maximum allowable dissipation  
Where:  
PD = Worst case actual power dissipation  
VINMAX  
Actual power dissipation:  
= Maximum voltage on VIN  
VOUTMIN = Minimum regulator output voltage  
ILOADMAX = Maximum output (load) current  
PD (VINMAX – VOUTMIN)ILOADMAX  
= [(3.0 x 1.1) – (2.7 x .995)]250 x 10–3  
= 155mW  
The maximum allowable power dissipation (Equation  
4-2) is a function of the maximum ambient temperature  
(TAMAX), the maximum allowable die temperature  
(TJMAX) and the thermal resistance from junction-to-air  
(JA). The 8-Pin SOIC package has a JA of approxi-  
mately 160°C/Watt, while the 8-Pin MSOP package  
has a JA of approximately 200°C/Watt.  
Maximum allowable power dissipation:  
PDMAX = (TJMAX TAMAX  
)
JA  
= (125 – 55)  
200  
= 350mW  
In this example, the TC1174 dissipates a maximum of  
155mW; below the allowable limit of 350mW. In a  
similar manner, Equation 4-1 and Equation 4-2 can be  
used to calculate maximum current and/or input  
voltage limits. For example, the maximum allowable  
VIN is found by substituting the maximum allowable  
power dissipation of 350mW into Equation 4-1, from  
which VINMAX = 4.1V.  
4.3  
Layout Considerations  
The primary path of heat conduction out of the package  
is via the package leads. Therefore, layouts having a  
ground plane, wide traces at the pads, and wide power  
supply bus lines combine to lower JA and therefore  
increase the maximum allowable power dissipation  
limit.
