? 2006 microchip technology inc. ds21663c-page 9 tc2054/2055/2186 4.0 detailed description the tc2054, tc2055 and tc2186 are precision fixed output voltage regulators. (if an adjustable version is desired, refer to the tc1070/tc1071/tc1187 data sheet (ds21353). unlike bipolar regulators, the tc2054, tc2055 and tc2186 supply current does not increase with load current. in addition, v out remains stable and within regulation over the entire 0 ma to maximum output current operating load range. figure 4-1 shows a typical application circuit. the regulator is enabled any time the shutdown input (shdn ) is at or above v ih , and shutdown (disabled) when shdn is at or below v il . shdn may be con- trolled by a cmos logic gate, or i/o port of a microcon- troller. if the shdn input is not required, it should be connected directly to the input supply. while in shut- down, supply current decreases to 0.05 a (typical), v out falls to zero volts, and error is open-circuited. figure 4-1: typical application circuit. 4.1 error open-drain output error is driven low whenever v out falls out of regulation by more than -5% (typical). this condition may be caused by low input voltage, output current limiting or thermal limiting. the error threshold is 5% below rated v out regardless of the programmed out- put voltage value (e.g. error = v ol 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 v out falls to v th , and inactive when v out rises above v th by v hys . 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 c 2 ). r 1 x c 2 should be chosen to maintain error below v ih of the processor reset input for at least 200 m s to allow time for the system to stabilize. pull-up resistor r 1 can be tied to v out , v in or any other voltage less than (v in + 0.3v). the error pin sink current is self-limiting to approximately 18 ma. figure 4-2: error output operation. 4.2 output capacitor a 1 f (min) capacitor from v out to ground is required. the output capacitor should have an effective series resistance of 0.01 . to 5 for v out = 2.5v, and 0.05 . to 5 for v out < 2.5v. ceramic, tantalum and aluminum electrolytic capacitors can be used. (since many aluminum electrolytic capacitors freeze at approximately -30c, solid tantalums are recommended for applications operating below -25c). when operating from source s 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. 4.3 input capacitor a 1 f capacitor should be connected from v in to gnd if there is more than 10 inches of wire between the regulator and this ac filter capacitor, or if a battery is used as the power source. aluminum electrolytic or tantalum capacitors can be used (since many aluminum electrolytic capa citors freeze at approxi- mately -30c, solid tantalum are recommended for applications operating below -25c). when operating from sources other than batteries, supply-noise rejection and transient response can be improved by increasing the value of t he input and output capacitors and employing passive filtering techniques. 0.2 f c 2 r 1 1m v+ c2 required only if error is used as a processor reset signal (see text) shutdown control (to cmos logic or tie to v in if unused) battlow or reset tc2054 tc2055 tc2186 v in battery v out gnd 1f v out 1f c 1 error shdn v ih v ol error v th v out hysteresis (v hys )
tc2054/2055/2186 ds21663c-page 10 ? 2006 microchip technology inc. 5.0 thermal considerations 5.1 thermal shutdown integrated thermal protection circuitry shuts the regula- tor off when the die temperature exceeds approxi- mately 160c. the regulator remains off until the die temperature cools to approximatley 150c. 5.2 power dissipation the amount of power the regulator dissipates is primarily a function of input and output voltage, and output current. equation 5-1 is used to calculate worst case power dissipation: equation 5-1: the maximum allowable power dissipation (equation 5-2) is a function of the maximum ambient temperature (t a max ), the maximum allowable die temperature (125 c) and the thermal resistance from junction-to-air ( ja ). the 5-pin sot-23a package has a ja of approximately 220c/watt when mounted on a typical two layer fr4 dielectric copper clad pc board. equation 5-2: equation 5-1 can be used in conjunction with equation 5-2 to ensure regulator thermal operation is within limits. for example: actual power dissipation: maximum allowable power dissipation: in this example, the tc2054 dissipates a maximum of only 26.7 mw; far below the allowable limit of 318 mw. in a similar manner, equation 5-1 and equation 5-2 can be used to calculate maximum current and/or input voltage limits. 5.3 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. p d v inmax v outmin ?
