TC1300
300 mA CMOS LDO with Shutdown, Bypass and
Independent Delayed Reset Function
Features
General Description
• LDO with Integrated Microcontroller Reset
Monitor Functionality
The TC1300 combines a low dropout regulator and a
microcontroller reset monitor in an 8-Pin MSOP pack-
age. Total supply current is 80 µA (typical), 20 to 60
times lower than bipolar regulators.
• Low Input Supply Current (80 µA, typical)
• Very Low Dropout Voltage
The TC1300 has a precise output with a typical accu-
racy of ±0.5%. Other key features include low noise
operation, low dropout voltage and internal feed-
forward compensation for fast response to step
changes in load. The TC1300 has both over-tempera-
ture and over-current protection. When the shutdown
control (SHDN) is low, the regulator output voltage falls
to zero, RESET output remains valid and supply cur-
rent is reduced to 30 µA (typical). The TC1300 is rated
for 300 mA of output current and stable with a 1 µF out-
put capacitor.
• 10 µsec (typ.) Wake-Up Time from SHDN
• 300 mA Output Current
• Standard or Custom Output and Detected
Voltages
• Power-Saving Shutdown Mode
• Bypass Input for Quiet Operation
• Separate Input for Detected Voltage
• 140 msec Minimum RESET Output Duration
• Space-Saving MSOP Package
• Specified Junction Temperature Range:
-40°C to +125°C
An active-low RESET is asserted when the detected
voltage (VDET) falls below the reset voltage threshold.
The RESET output remains low for 300 msec (typical)
after VDET rises above reset threshold. The TC1300
also has a fast wake-up response time (10 µsec.,
typical) when released from shutdown.
Applications
• Battery-Operated Systems
• Portable Computers
• Medical Instruments
• Pagers
• Cellular / GSM / PHS Phones

TC1300, the selected output capacitor equivalent
series resistance (ESR) range is 0.1 ohms to 5 ohms
when using 1 µF of output capacitance, and 0.01 ohms
to 5 ohms when using 10 µF of output capacitance.
Because of the ESR requirement, tantalum and alumi-
num electrolytic capacitors are recommended. Alumi-
num electrolytic capacitors are not recommended for
operation at temperatures below -25°C. When operat-
ing from sources other than batteries, rejection and
transient responses can be improved by increasing the
value of the input and output capacitors and employing
passive filtering techniques.

DETAILED DESCRIPTION
The TC1300 is a combination of a fixed output, low
dropout
regulator
and
a
microcontroller
monitor/RESET. Unlike bipolar regulators, the TC1300
supply current does not increase with load current. In
addition, VOUT remains stable and within regulation
over the entire specified operating load range (0 mA to
300 mA) and operating input voltage range (2.7V to
6.0V).
Figure 3-1 shows a typical application circuit. The reg-
ulator is enabled any time the shutdown input (SHDN)
is above VIH. The regulator is shutdown (disabled)
when SHDN is at or below VIL. SHDN may be con-
trolled by a CMOS logic gate or an I/O port of a micro-
controller. If the SHDN input is not required, it should be
connected directly to the input supply. While in shut-
down, supply current decreases to 30 µA (typical),
VOUT falls to zero and RESET remains valid.
3.3
Bypass Input (Optional)
An optional 470 pF capacitor connected from the
Bypass input to ground reduces noise present on the
internal reference, which in turn significantly reduces
output noise and improves PSRR performance. 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.
3.1
RESET Output
The RESET output is driven active-low within 160 µsec
of VDET falling through the reset voltage threshold.
RESET is maintained active for a minimum of
140 msec after VDET rises above the reset threshold.
The TC1300 has an active-low RESET output. The out-
put of the TC1300 is valid down to VDET = 1V and is
optimized to reject fast transient glitches on the VDET
line.
3.4
Turn On Response
The turn-on response is defined as two separate
response categories, Wake-Up Time (tWK) and Settling
Time (tS).
The TC1300 has a fast Wake-Up Time (10 µsec typi-
cal) when released from shutdown. See Figure 3-2 for
the Wake-Up Time designated as tWK. The Wake-Up
Time is defined as the time it takes for the output to rise
to 2% of the VOUT value after being released from
shutdown.

3.2 Output Capacitor
tWK
A 1 µF (min) capacitor from VOUT to ground is required.
A 1 µF capacitor should also 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. As with all low dropout
regulators, a minimum output capacitance is required
to stabilize the output voltage. For the TC1300, a mini-
mum of 1 µF of output capacitance is enough to stabi-
lize the device over the entire operating load and line
range. The selected output capacitor plays an impor-
tant role is compensating the LDO regulator. For the

The worst case actual power dissipation equation can
be used in conjunction with the LDO maximum allow-
able power dissipation equation to ensure regulator
thermal operation is within limits. For example:

THERMAL CONSIDERATIONS
Thermal Shutdown
Integrated thermal protection circuitry shuts the regula-
tor off when the die temperature exceeds 150°C. The
regulator remains off until the die temperature drops to
approximately 140°C.

Power Dissipation
The amount of power the regulator dissipates is primar-
ily a function of input and output voltage, and output
current. The following equation is used to calculate
worst case actual power dissipation:

PD VINMAX – VOUTMINILOADMAX
PD VINMAX – VOUTMINILOADMAX

PD = worst case actual power dissipation
= 220 mW
VINMAX = maximum voltage on VIN
VOUTMIN = minimum regulator output voltage
ILOADMAX = maximum output (load) current
EQUATION:
MAXIMUM ALLOWABLE
POWER DISSIPATION
The maximum allowable power dissipation, PDMAX, is a
function of the maximum ambient temperature (TAMAX),
the maximum recommended die temperature (125°C)
and the thermal resistance from junction-to-air (JA).
The MSOP-8 package has a JA of approximately
200°C/Watt when mounted on a FR4 dielectric copper
clad PC board.

= 350 mW
In this example, the TC1300 dissipates a maximum of
only 220 mW; below the allowable limit of 350 mW. In a
similar manner, the maximum actual power dissipation
equation and the maximum allowable power dissipa-
tion equation can be used to calculate maximum cur-
rent and/or input voltage limits. For example, the
maximum allowable VIN is found by substituting the
maximum allowable power dissipation of 350 mW into
the actual power dissipation equation, from which
VINMAX = 4.97V.

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.
