FEATURES
GENERAL DESCRIPTION
The TC1014, TC1015, and TC1185 are high accuracy
(typically ±0.5%) CMOS upgrades for older (bipolar) low drop-
out regulators such as the LP2980. Designed specifically for
battery-operated systems, the devices’ CMOS construction
eliminates wasted ground current, significantly extending bat-
tery life. Total supply current is typically 50µA at full load (20 to
60 times lower than in bipolar regulators!).
Keyfeaturesforthedevicesincludeultralow-noiseopera-
tion(plusoptionalBypassinput),fastresponsetostepchanges
inload,andverylowdropoutvoltage,typically85mV(TC1014),
180mV (TC1015), and 270mV (TC1185) at full load. Supply
current is reduced to 0.5µA (max) and VOUT falls to zero when
the shutdown input is low. The devices also incorporate both
over-temperature and over-current protection.

NOTES: 1. The minimum VIN has to meet two conditions: VIN ≥ 2.7V and VIN ≥ VR + VDROPOUT
.
2. VR is the regulator output voltage setting. For example: VR = 1.8V, 2.5V, 2.7V, 2.8V, 2.85V, 3.0V, 3.3V, 3.6V, 4.0V, 5.0V.

4. Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range from 1.0mA
to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal regulation specification.
5. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value at a 1V differential.
6. 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 = 10msec.
7. Themaximumallowablepowerdissipationisafunctionofambienttemperature, themaximumallowablejunctiontemperatureandthethermal

Bypass Input
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 TC1014, TC1015, and TC1185 are precision fixed
output voltage regulators. (If an adjustable version is de-
sired, please see the TC1070, TC1071, or TC1187 data
sheets.) Unlike bipolar regulators, the TC1014, TC1015,
and TC1185 supply current does not increase with load
current. In addition, VOUT remains stable and within regula-
tion at very low load currents (an important consideration in
RTC and CMOS RAM battery back-up applications).
Figure 1 shows a typical application circuit. The regula-
tor 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 0.05µA
(typical) and VOUT falls to zero volts.
Output Capacitor
A 1µF (min) capacitor from VOUT to ground is required.
The output capacitor should have an effective series resis-
tance of 5Ω or less. A 1µF 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
Integrated thermal protection circuitry shuts the regula-
tor off when die temperature exceeds 160°C. The regulator
remains off until the die temperature drops to approximately
150°C.

Equation 1.
In this example, the TC1014 dissipates a maximum of
only 26.7 mW; far below the allowable limit of 318 mW. In a
similar manner, Equation 1 and Equation 2 can be used to
calculate maximum current and/or input voltage limits.
The maximum allowablepower dissipation (Equation 2)
is a function of the maximum ambient temperature (TAMAX),
the maximum allowable die temperature (125°C) and the
thermal resistance from junction-to-air (θJA). The
5-Pin SOT-23A package has a θJA of approximately 220°C/
Watt when mounted on a single layer FR4 dielectric copper
clad PC board.
Layout Considerations
The primary path of heat conduction out of the package
isviathepackageleads. Therefore, layoutshavingaground
plane, wide traces at the pads, and wide power supply bus
lines combine to lower θJA and, therefore, increase the
maximum allowable power dissipation limit.

ILOAD was increased until temperature of die reached about 160°C, at which time
integrated thermal protection circuitry shuts the regulator off when die
temperature exceeds approximately 160°C. The regulator remains off until die
temperature drops to approximately 150°C.
