ts5204 150ma low noise ldo voltage regulator 3 / 8 version: d07 application information ts5204 series is designed to provide 150ma (5v version) of continuous current in a very small package. maximum power dissipation can be calculated based on the output current and the voltage drop across the part. to determine the maximum power dissipation of the package, use the junction - ambient thermal resistanc e of the device and the following basic equation: p d(max) = [ t j(max) 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 the equation: p d = (v in v out ) * i out + v in * i gnd substituting 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 ts5204cx33 at room temperature with a minimum footprint layout, the maximum input voltage for a set output current can be determined as follows: p d(max) = (125 o c 25 o c) / 220 o c/w the junction to ambie nt thermal resistance for the minimum footprint is 220 o c/w, the maximum power dissipation must not be exceeded for proper operation. using the output voltage of 3.3v and an output current of 120ma, the maximum input voltage can be determined. from th e elec trical characteristics table, the maximum ground current for 120ma output current is 2.5ma. 445mw = (v in 3.3v ) * 120ma + v in * 2.5ma 445mw = v in * 120ma 3.3 * 120ma + v in * 2.5ma 445mw = v in * 120ma 395mw + v in * 2.5ma 840mw = v in * 122.5ma v in (max ) = 6.85v therefore, a 3.3v application at 120ma of output current can accept a maximum input voltage of 6.85v in a sot - 23 package. input capacitor requirement an input capacitor of 0.1uf 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 ts5204 series requires an output capacitor to maintain stability and improve transient response is necessary. 2.2uf minimum is recommended. larger values imp rove the regulator s transient response. the output capacitor 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 low amplitude oscillation on the output and/or under damped transient response. most of tantalum or aluminum electrolytic capacitors are adequate; film types will work. since many aluminum electrolytic have electrolytes that freeze at about 30 o c, solid tantalums are recommended for operation below 25 o c. at lower values of output current, less output capacitance 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 stabil ity the ts5204 series will remain stable and in regulation with no load, unlike many other voltage regulators. this is especially important in cmos ram keep alive applications. dual supply operation when used in dual supply systems where the regulator load is returned to a negative supply, the output voltage must be diode clamped to ground.
