General Description
The TC1054, TC1055 and TC1186 are high accuracy
(typically 0.5%) CMOS upgrades for older (bipolar)
low dropout regulators. Designed specifically for
battery-operated
systems,
the
devices'
CMOS
construction
eliminates
wasted
ground
current,
significantly extending battery life. Total supply current
is typically 50
A at full load (20 to 60 times lower than
in bipolar regulators).
The devices' key features include ultra low noise
operation, very low dropout voltage typically 85mV
(TC1054); 180mV (TC1055); and 270mV (TC1186) at
full load -- and fast response to step changes in load.
An error output (ERROR) is asserted when the devices
are out-of-regulation (due to a low input voltage or
excessive output current). ERROR can be used as a
low battery warning or as a processor RESET signal
(with the addition of an external RC network). Supply
current is reduced to 0.5
A (max) and both V
OUT
and
ERROR are disabled when the shutdown input is low.
The devices incorporate both over-temperature and
over-current protection.
The TC1054, TC1055 and TC1186 are stable with an
output capacitor of only 1
F and have a maximum
output
current
of
50mA,
100mA
and
150mA,
respectively. For higher output current regulators,
please see the TC1173 (I
OUT
= 300mA) data sheet.

DETAILED DESCRIPTION
The TC1054, TC1055 and TC1186 are precision fixed
output voltage regulators. (If an adjustable version is
desired, please see the TC1070/TC1071/TC1187 data
sheet.) Unlike bipolar regulators, the TC1054, TC1055
and TC1186 supply current does not increase with load
current. In addition, V
OUT
remains stable and within
regulation over the entire 0mA to I
OUT
MAX
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 V
IH
, and shutdown (disabled)
when SHDN is at or below V
IL
. 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 0.05
A
(typical), V
OUT
falls to zero volts, and ERROR is open-
circuited.
FIGURE 3-1:
TYPICAL APPLICATION
CIRCUIT
3.1
ERROR Open Drain Output
ERROR is driven low whenever V
OUT
falls out of
regulation by more than 5% (typical). This condition
may be caused by low input voltage, output current
limiting, or thermal limiting. The ERROR threshold is
5% below rated V
OUT
regardless of the programmed
output voltage value (e.g. ERROR = V
OL
at 4.75V (typ.)
for a 5.0V regulator and 2.85V (typ.) for a 3.0V
regulator). ERROR output operation is shown in
Figure 3-2.
Note that ERROR is active when V
OUT
falls to V
TH
, and
inactive when V
OUT
rises above V
TH
by V
HYS
.
As shown in Figure 3-1, ERROR can be used as a
battery low flag, or as a processor RESET signal (with
the addition of timing capacitor C2). R1 x C2 should be
chosen to maintain ERROR below V
IH
of the processor
RESET input for at least 200 msec to allow time for the
system to stabilize. Pull-up resistor R1 can be tied to
V
OUT
, V
IN
or any other voltage less than (V
IN
+ 0.3V).
FIGURE 3-2:
ERROR OUTPUT
OPERATION
3.2
Output Capacitor
A 1
F (min) capacitor from V
OUT
to ground is
recommended. The output capacitor should have an
effective series resistance greater than 0.1
and less
than 5.0
, and a resonant frequency above 1MHz. A
1
F capacitor should be connected from V
IN
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 approxi-
mately -30C, solid tantalums are recommended for
applications operating below -25C.) 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
4.1
Thermal Shutdown
Integrated
thermal
protection
circuitry
shuts
the
regulator off when die temperature exceeds 160C.
The regulator remains off until the die temperature
drops to approximately 150C.
4.2
Power Dissipation
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:
EQUATION 4-1:
The
maximum
allowable
power
dissipation
(Equation 4-2) is a function of the maximum ambient
temperature (T
A
MAX
), the maximum allowable die
temperature (T
J
MAX
) and the thermal resistance from
junction-to-air (
JA
). The 5-Pin SOT-23A package has
a
JA
of approximately 220C/Watt.
EQUATION 4-2:
Equation 4-1
can
be
used
in
conjunction
with
Equation 4-2 to ensure regulator thermal operation is
within limits. For example:
Given:
V
IN
MAX
= 3.0V 5%
V
OUT
MIN
= 2.7V 2.5%
I
LOAD
MAX
= 40mA

)I
LOAD
MAX
= [(3.0 x 1.05) (2.7 x .975)]40 x 10

= 20.7mW
Maximum allowable power dissipation:
In this example, the TC1054 dissipates a maximum of
20.7mW; below the allowable limit of 318mW. In a
similar manner, Equation 4-1 and Equation 4-2 can be
used to calculate maximum current and/or input
voltage limits.
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.
