•
•
The TC1267 is an application-specific, low dropout
regulator (LDO), specifically intended for use in PCI
peripheral card applications complying with PCI Power
Management (PCI 2.0). It provides an uninterrupted,
3.3V output voltage when the main (5V) or auxiliary
(3.3V) input voltage supplies are present.

Pin Configuration
The TC1267 consists of an LDO, a voltage threshold
detector, external switchover logic and gate drive
circuitry. It functions as a conventional LDO as long as
the voltage on the main supply input (VIN) is above the
lower threshold (3.90V typical). Should the voltage on
VIN fall below the lower threshold, the LDO is disabled
and an external P-channel MOSFET is automatically
turned on, connecting the auxiliary supply input to
VOUT, and ensuring an uninterrupted 3.3V output. The
main supply is automatically selected, if both the main
and auxiliary input supplies are present, and transition
from one input supply to the other is ensured glitchfree. High integration, automatic secondary supply switchover, Kelvin sensing, and small size make the
TC1267 the optimum LDO for PCI 2.0 applications.

THERMAL CONSIDERATIONS
4.1
Thermal Shutdown
Integrated thermal protection circuitry shuts the
regulator off when die temperature exceeds 160°C.
The regulator remains off until the die temperature
drops to approximately 150°C.
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:
Equation 4-1 can be used in conjunction with
Equation 4-2 to ensure regulator thermal operation is
within limits. For example:
Given:
VINMAX
= 5V ± 5%
VOUTMIN = 3.217V
ILOADMAX = 400mA
TJMAX
= 95°C
TAMAX
= 70°C
JA
= 27°C/W (DDPAK mounted on
1000 sq mm topside copper area)
Find: 1. Actual power dissipation
2. Maximum allowable dissipation
Actual power dissipation:
PD  (VINMAX – VOUTMIN)ILOADMAX
PD  (VINMAX – VOUTMIN)ILOADMAX
Where:
= (5.25V - 3.217V) 400mA
PD = Worst case actual power dissipation
VINMAX = Maximum voltage on VIN
VOUTMIN = Minimum regulator output voltage
ILOADMAX = Maximum output (load) current
= 813mW
The
maximum
allowable
power
dissipation
(Equation 4-2) is a function of the maximum ambient
temperature (TAMAX), the maximum allowable die
temperature (TJMAX) and the thermal resistance from
junction-to-air (JA).
Maximum allowable power dissipation:
PDMAX = (TJMAX – TAMAX)
JA
= (95 – 70)
27
= 423mW
In this example, the TC1267 dissipates a maximum of
813mW; below the allowable limit of 926mW.
EQUATION 4-2:
PDMAX = (TJMAX – TAMAX)
JA
Where all terms are previously defined.
Table 4-1 shows various values of JA for the TC1267
packages.
