Description
The TC1263 is a fixed-output, high-accuracy (typic ally
±0.5%) CMOS low dropout regulator. Designed
specifically for battery-operated systems, the TC1263’ s
CMOS construction eliminates wasted ground current,
signific antly extending battery life. Total supply current
is typic all y 80 µA at full lo ad (20 to 60 tim es lower tha n
in bipolar regulators).
TC1263 ke y features incl ude ul tra 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.

3.0 PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 3-1.

3.1 Regulated Output Voltage (VOUT)
VOUT is a regulated voltage output.
3.2 Ground (GND)
Ground terminal.
3.3 Reference Bypass (BYPASS)
Reference bypass input. Connect a 470 pF to the
BYPASS input to further reduce output noise.

Out-of-Regulation Flag (open-drain output). ERROR
goes low when VOUT is out-of-tolerance by
approximately – 5%.
3.5 Shutdown Control (SHDN)
Shutdown control input. The regulator is fully enabled
when a logic-high is applied to SHDN. The regulator
enters shutdown when a logic-low is applied to this
input. D uring s hutdown , output v oltage falls t o zero an d

TC1263
4.0 DETAILED DESCRIPTION
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
0mA to I
LOADMAX load current range (an important
consid eration in RTC and CM OS R AM batt ery back-u p
applications).
Figure 4-1 shows a typical application circuit.
FIGURE 4-1: Typi c al App lica tio n Circui t.
4.1 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 0.1 and less
than 5. 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.
4.2 ERROR Output
ERROR is driven low whenever VOUT falls out of
regulati on by more th an – 5% (typ.). This condition may
be caused by low input voltage, output current limiting
or thermal limiting. The ERROR th reshold i s 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 si gnal ( with
the addition of timing capacitor C3). R1 x C3 should be
chosen to maint ain ERR OR 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).

5.0 THERMAL CONSIDER ATION S
5.1 Thermal Shutdown
Integrated thermal protection circuitry shuts the
regulato r off when the die tem peratu re exceed s 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
primaril y a funct ion of inp ut and outp ut volt age and o ut-
put curre nt. Th e fo llowing equation is use d to calculate
worst-case actual power dissipation:
EQUATION 5-1:
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 (JA).
EQUATION 5-2:
Table 5-1 and Table 5-2 show various values of JA
for
the TC1263 package ty pes.

GUIDELINES FOR TC1263 IN
8-PIN SOIC PACKAGE
TABLE 5-2: THERMAL RESISTANCE
GUIDELINES FOR TC1263 IN
5-PIN DDPAK/TO-220
PACKAGE
Equation 5-1 can be used in conjunction with
Equation 5-2 to ensure regulator thermal operation is
within limits. For ex ample:
Find:
1. Actual power dissipation
2. Maximum allowable dissipation
Actual po wer dissipation:
Maximum allowable power dissipation:
In this example, the TC1263 diss ipates 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 t he 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 intellec tual 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 c onstantly evolving. We a t Microc hip are co m mitted to continuously improving the code prot ect ion featur es 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.
Microchip received ISO/TS-16949:2009 certification for its worldwide
headquarters, design and wafer fabrication facilities in Chandler and
Tempe, Arizona; Gresham, Oregon and design centers in California
and India. The Company’s quality system processes and procedures
are for its PIC® MCUs and dsPIC® DSCs, KEELOQ® co de hopping
devices, Serial EEPROMs, microperiph erals, nonvolatile memory and
analog products. In addition, Microchip’s quality system for the design
and manufacture of development systems is ISO 9001:2000 certified.
