| TC1264 800 mA Fixed-Output CMOS LDO with Shutdown Features * * * * * Very Low Dropout Voltage 800 mA Output Current High Output Voltage Accuracy Standard or Custom Output Voltages Overcurrent and Overtemperature Protection Description The TC1264 is a fixed output, high accuracy (typically 0.5%) CMOS low dropout regulator. Designed specifically for battery-operated systems, the TC1264's CMOS construction eliminates wasted ground current, significantly extending battery life. Total supply current is typically 80 A at full load (20 to 60 times lower than in bipolar regulators). TC1264 key features include ultra low noise operation, very low dropout voltage (typically 450 mV at full load), and fast response to step changes in load. The TC1264 incorporates both over temperature and over current protection. The TC1264 is stable with an output capacitor of only 1F and has a maximum output current of 800 mA. It is available in 3-Pin SOT-223, 3-Pin TO-220 and 3-Pin DDPAK packages.

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 1.5V differential.

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, JA).

DS21375C-page 5 TC1264 4.0 DETAILED DESCRIPTION 4.1 Output Capacitor The TC1264 is a precision, fixed output LDO. Unlike bipolar regulators, the TC1264's supply current does not increase with load current. In addition, VOUT remains stable and within regulation over the entire 0mA 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. A 1 F (min) capacitor from VOUT to ground is required. The output capacitor should have an effective series resistance greater than 0.1 and less than 5. A 1 F capacitor should 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. Aluminum electrolytic or tantalum capacitor types can be used. (Since many aluminum electrolytic capacitors freeze at approximately -30C, solid tantalums 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 the input and output capacitors and employing passive filtering techniques.

The following equation is used to calculate worst-case actual power dissipation: * Tab of device attached to topside copper Equation 5-1 can be used in conjunction with Equation 5-2 to ensure regulator thermal operation is within limits. For example: Given: VINMAX = 3.3V 10% VOUTMIN = 2.7V 0.5% ILOADMAX = 275 mA TJMAX = 125C TAMAX = 95C JA = 59C/W (SOT-223) Find: 1. Actual power dissipation. 2. Maximum allowable dissipation Actual power dissipation: P D ( V INMAX - V OUTMIN )I LOADMAX P D = ( 3.3 x 1.1 ) - ( 2.7 x .995 ) 275 x 10 P D = 260 mW Maximum allowable power dissipation: T JMAX - T AMAX P DMAX = ------------------------------------- JA ( 125 - 95 ) P DMAX = ------------------------59 P DMAX = 508 mW In this example, the TC1264 dissipates a maximum of 260 mW; below the allowable limit of 508 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 508mW into Equation 5-1, from which VINMAX = 4.6V. -3 EQUATION 5-1: P D = ( V INMAX - V OUTMIN )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 (JA). EQUATION 5-2: PDMAX = (TJMAX - TAMAX) JA Where all terms are previously defined. Table 5-1 and Table 5-2 show various values of JA for the TC1264 packages.
