N ote 2: The max imum allowable pow er dissipation at any Ta is Pd(max) = [TJ(MAX) - Ta] + ӨJA. Exceeding the maximum allowable power dissipation w ill result in excessive die temperature, and the regulator will go into ther mal shutdown. N ote 3: Dev ices are ESD sensitive. H andling precautions recommended. N ote 4: The device is not guaranteed to func tion outs ide its operating rating. N ote 5: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range. Note 6: Regulation is measured at cons tant junction temperature using low duty cycle pulse tes ting. Par ts are tested for load regulation in the load range from 1mA to 80mA. Changes in output voltage due to heating effec ts are covered by the ther mal regulation specification. Note 7: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. Note 8: Ground pin current is the regulator quies cent current plus pass transistor base current. The total current drawn from the supply is the sum of the load current plus the ground pin current. Note 9: Ther mal regulation is defined as the change in output v oltage at a time “t” after a change in pow er dissipation is applied, excluding load or line regulation effec ts. Specifications are for a 80mA load pulse at VIH =16V for t=10mS. Application Information Enable I nput TS5213 series feature an active-high (>2V) enable ( EN) input that allows ON /OFF control of the regulator. Current drain reduces to “zero” when the device is shutdow n, with only micro-amperes of leakage current. The EN is compatible with C MOS logic interfacing. EN may be dir ectly tied to VIH and pulled up to the maximum supply voltage. Input Capacitor Requirement An input capacitor of 0.17uF or greater is recommended when the device is more than 10” away from the bulk AC supply capacitance or when the supply is a battery . Output Capacitor Requirement The TS5213 series requires an output capacitor to maintain s tability and improve transient response is nec essary. The TS5213 is ultra stable, requir ing only 0.47uF of output capacitance for stability. It is stable w ith all type of capacitors, including the tiny, low- ESR ceramic chip capacitors. The output capac itor value may be increased without limit. No Load Stability The TS5213 series will remain s table and in regulation w ith no load, unlike many other voltage regulators. This is especially important in C MOS R AM keep alive applications. Fixed Output Regulator Application VIN EN of f on VOUT COUT 0.47uF TS5213 ser ies is offered a smaller system solution, it is only required a s mall multilayer ceramic capacitor for stability.

Maximum power dissipation can be calculated based on the output cur rent and the voltage drop across the part. To deter mine the maximum power dissipation of the package, use the junction-ambient thermal resis tance of the dev ice and the following basic equation: PD(MAX) = [ TJ(MAX) – TA ] /ΘJA TJ(MAX) is the max imum junc tion temperature of the die(125 C), and Ta is the ambient operating temper ature. ΘJA is layout dependent, the ac tual pow er dissipation of the regulator circuit can be deter mined using the equation: PD = (VIN – VOUT) * IOUT + VIN * IGND Subs tituting Pd( max) for Pd and solving for the operating conditions that are critical to the application will give the maximum operating conditions for the regulator circuit. For example, when operating the TS5213CX550 at room temperature w ith a minimum footprint layout, the maximum input voltage for a set output current can be determined as follows: o o o PD(MAX) = (125 C – 25 C) / 220 C/W PD(MAX) = 455 mW The junction to ambient ther mal resistance for the minimum footprint is 220 C/W, the maximum power dis sipation must not be exceeded for proper operation. Using the output voltage of 5.0V and an output current of 80mA, the maximum input voltage can be determined. For m the electrical charac teristics table, the max imum gr ound curr ent for 80mA output current is 1mA. 445mW = ( VIN – 5.0V ) * 80mA + VIN * 1.8mA 445mW = VIN * 80mA – 5.0 * 80mA + VI N * 1.8mA 445mW = VIN * 80mA – 400mW + VIN * 1.8mA 845mW = VIN * 81.8mA VIN ( max) = 10.33V Therefore, a 5.0V application at 80mA of output current can accept a maximum input voltage of 10.33V in a SOT-25 pac k age. o o 4/8 Version: B07 T S5 2 1 3 80mA Low Noise LDO Voltage Regulator with Enable Function Electrical Characteristics Curve Fi gure 1.
