Document Number: DS_P0000201 1 Version: G15 80mA Low Noise LDO Voltage Regulator with Enable Function GENERAL DESCRIPTION TS5213 is an efficient linear voltage regulator wit h ultra- low noise output, very low dropout voltage (typical ly 50mV at light loads and 320mV at 80mA), and very lo w ground current (225μA at 20mA), providing high outp ut current even when the application requires very low dropout voltage. The Chip Enable (EN) includes a CMOS or TTL compatible input allows the output to b e turned off to prolong battery life. When shutdown, power consumption drops nearly to zero. TS5213 is included a precision voltage reference, error corre ction circuit, a current limited output driver, over temp erature shutdown and revered battery protection.

APPLICATION INFORMATION
TS5213 series feature an active-high (>2V) enable ( EN) input that allows ON/OFF control of the regulat or. Current drain reduces to “zero” when the device is shutdown, with only micro-amperes of leakage curren t. The EN is compatible with CMOS logic interfacing. EN ma y be directly tied to V IH and pulled up to the maximum supply voltage. Input Capacitor Requirement An input capacitor of 0.17μF or greater is recommen ded 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 stability and improve transient response is necessary. The TS5213 is ultra-stable, requiring only 0.47uF o f output capacitance for stability. It is stable wi th all type of capacitors, including the tiny, low-ESR ceramic chi p capacitors. The output capacitor value may be inc reased without limit. No Load Stability The TS5213 series will remain stable and in regulat ion with no load, unlike many other voltage regulat ors. This is especially important in CMOS RAM keep alive applications.
Document Number: DS_P0000201 5 Version: G15 APPLICATION INFORMATION (CONTINUE) Thermal Characteristics TS5213 series is designed to provide 80mA of contin uous current in a very small package. Maximum power dissipation can be calculated based on the output c urrent and the voltage drop across the part. To det ermine the maximum power dissipation of the package, use the j unction-ambient thermal resistance of the device an d the following basic equation: PD(MAX) = [ T J(MAX) – TA ] /ΘJA TJ(MAX) is the maximum junction temperature of the die(125 oC), and Ta is the ambient operating temperature. Θ JA is layout dependent, the actual power dissipation of the regulator circuit can be determined using the equation: PD = (V IN – VOUT ) * I OUT + V IN * I GND Substituting P D(MAX) for P D and solving for the operating conditions that are critical to the application will give the maximum operating conditions for the regulator circ uit. For example, when operating the TS5213CX550 at room temperature with a minimum footprint layout, the ma ximum input voltage for a set output current can be determined as follows: PD(MAX) = (125 oC – 25 oC) / 220 oC/W PD(MAX) = 455mW The junction to ambient thermal resistance for the minimum footprint is 220 oC/W, the maximum power dissipation must not be exceeded for proper operation. Using th e output voltage of 5.0V and an output current of 8 0mA, the maximum input voltage can be determined. Form the e lectrical characteristics table, the maximum ground current for 80mA output current is 1mA. 445mW = (V IN – 5.0V ) * 80mA + V IN * 1.8mA 445mW = V IN * 80mA – 5.0 * 80mA + V IN * 1.8mA 445mW = V IN * 80mA – 400mW + V IN * 1.8mA 845mW = V IN * 81.8mA VIN (max) = 10.33V Therefore, a 5.0V application at 80mA of output cur rent can accept a maximum input voltage of 10.33V i n a SOT- 25 package.
