ts5204 150ma low noise ldo voltage regulator 3/8 version: f11 application information ts5204 series is designed to provide 150ma (5v vers ion) of continuous current in a very small package. maximum power dissipation can be calculated based o n the output current and the voltage drop across th e part. to determine the maximum power dissipation of the p ackage, use the junction-ambient thermal resistance of the device and the following basic equation: p d(max) = [ t j(max) C t a ] / ja tj(max) is the maximum junction temperature of the die(125 o c), and ta is the ambient operating temperature. ja is layout dependent, the actual power dissipation of the regulator circuit can be determined using th e equation: p d = (v in C v out ) * i out + v in * i gnd substituting pd(max) for pd and solving for the ope rating conditions that are critical to the applicat ion will give the maximum operating conditions for the regulator circ uit. for example, when operating the ts5204cx33 at room temperature with a minimum footprint layout, the ma ximum input voltage for a set output current can be determined as follows: p d(max) = (125 o c C 25 o c) / 220 o c/w the junction to ambient thermal resistance for the minimum footprint is 220 o c/w, the maximum power dissipation must not be exceeded for proper operation. using th e output voltage of 3.3v and an output current of 1 20ma, the maximum input voltage can be determined. from the e lectrical characteristics table, the maximum ground current for 120ma output current is 2.5ma. 445mw = (v in C 3.3v ) * 120ma + v in * 2.5ma 445mw = v in * 120ma C 3.3 * 120ma + v in * 2.5ma 445mw = v in * 120ma C 395mw + v in * 2.5ma 840mw = v in * 122.5ma v in (max) = 6.85v therefore, a 3.3v application at 120ma of output cu rrent can accept a maximum input voltage of 6.85v i n a sot- 23 package. input capacitor requirement an input capacitor of 0.1uf or greater is recommend ed when the device is more than 10 away from the b ulk ac supply capacitance or when the supply is a battery. output capacitor requirement the ts5204 series requires an output capacitor to m aintain stability and improve transient response is necessary. 2.2uf minimum is recommended. larger values improve the regulators transient response. the output cap acitor value may be increased without limit. the output capacitor should have an esr (effective series resistance) less than 5 and a resonant frequency above 1mhz. ultra low esr capacitors can cause a lo w amplitude oscillation on the output and/or under damped transient response. most of tantalum or aluminum el ectrolytic capacitors are adequate; film types will work. since many aluminum electrolytic have electrolytes that f reeze at about C30 o c, solid tantalums are recommended for operation below C25 o c. at lower values of output current, less output c apacitance is required for output stability. the capacitor can be reduced to 0.47uf for current below 10ma or 0.33uf for currents below 1ma . no load stability the ts5204 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 applica tions. dual supply operation when used in dual supply systems where the regulato r load is returned to a negative supply, the output voltage must be diode clamped to ground.
