•
•
•
•
•
The TC1263 is a fixed-output, high-accuracy (typically
±0.5%) CMOS low dropout regulator. Designed
specifically for battery-operated systems, the TC1263’s
CMOS construction eliminates wasted ground current,
significantly extending battery life. Total supply current
is typically 80 µA at full load (20 to 60 times lower than
in bipolar regulators).

•
•
TC1263 key features include ultra low noise operation,
very low dropout voltage (typically 350 mV at full load)
and fast response to step changes in load.
The TC1263 incorporates both overtemperature and
overcurrent protection. The TC1263 is stable with an
output capacitor of only 1 µF and has a maximum
output current of 500 mA. It is available in 8-Pin SOIC,
5-Pin TO-220 and 5-Pin DDPAK packages.

Regulation is measured at a constant junction temperature using low duty-cycle pulse testing. Load regulation is tested
over a load range from 0.1 mA to the maximum specified output current. Changes in output voltage due to heating
effects are covered by the thermal regulation specification.
Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal
value measured at a 1.0V differential.
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 ms.
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, θJA). Exceeding the maximum allowable power
dissipation causes the device to initiate thermal shutdown. Please see Section 5.0 “Thermal Considerations” for
more details.

DETAILED DESCRIPTION
4.2
The TC1263 is a precision, fixed-output LDO. Unlike
bipolar regulators, the TC1263’s supply current does
not increase with load current. In addition, VOUT
remains stable and within regulation over the entire
0 mA to ILOADMAX load current range (an important
consideration in RTC and CMOS RAM battery back-up
applications).
Figure 4-1 shows a typical application circuit.
ERROR Output
ERROR is driven low whenever VOUT falls out of
regulation by more than – 5% (typ.). This condition may
be caused by low input voltage, output current limiting
or thermal limiting. The ERROR threshold is 5% below
rated VOUT, regardless of the programmed output
voltage value (e.g., ERROR = VOL 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 4-2.
Note that ERROR is active when VOUT is at or below
VTH, and inactive when VOUT is above VTH + VHYS.

As shown in Figure 4-1, ERROR can be used as a
battery-low flag or as a processor RESET signal (with
the addition of timing capacitor C3). R1 x C3 should be
chosen to maintain ERROR below VIH of the processor
RESET input for at least 200 ms to allow time for the
system to stabilize. Pull-up resistor R1 can be tied to
VOUT, VIN or any other voltage less than (VIN + 0.3V).

Typical Application Circuit.
Output Capacitor
A 1 µF (min.) capacitor from VOUT to ground is
required. The output capacitor should have an Effective
Series Eesistance (ESR) greater than 0.1Ω and less
than 5Ω. A 1 µF capacitor should be connected from
VIN to GND if there is either more than 10 inches of wire
between the regulator and the AC filter capacitor or 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 by employing passive filtering
techniques.

THERMAL CONSIDERATIONS
5.1
Thermal Shutdown
Integrated thermal protection circuitry shuts the
regulator off when the die temperature exceeds 160°C.
The regulator remains off until the die temperature
drops to approximately 150°C.
5.2
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 5-1:
P D = ( V INMAX – VOUTMIN )I LOADMAX
Where:
PD = Worst-case actual power dissipation
VINMAX = Maximum voltage on VIN
VOUTMIN = Minimum regulator output voltage
ILOADMAX = Maximum output (load) current
The
maximum
allowable
power
dissipation
(Equation 5-2) is a function of the maximum ambient
temperature (TAMAX), the maximum allowable die
temperature (TJMAX) and the thermal resistance from
junction-to-air (θJA).

Equation 5-1 can be used in conjunction with

In this example, the TC1263 dissipates a maximum of
260 mW below the allowable limit of 500 mW. In a
similar manner, Equation 5-1 and Equation 5-2 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 500 mW into Equation 5-1, from
which VINMAX = 4.6V.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
