ts39300/1/2/3 3a ultra low dropout voltage regulator with multi - f unction 5 / 12 version: b07 application information the ts3930 0/1/2/3 are high performance with low dropout voltage regulator suitable for moderate to high current and voltage regulator application. its 630mv dropout voltage at full load and over temperature makes it especially valuable in battery power systems and as high efficiency noise filters in po st regulator applications. unlike normal npn transistor design, where the base to emitter voltage drop and collector to emitter saturation voltage limit the minimum dropout voltage, dropout performance of the pnp output of these devices is limited only by low v ce saturation voltage. the ts3930 0/1/2/3 is fully protected from damage due to fault conditions. linear current limiting is provided. output current during overload conditions is constant. thermal shutdown the device when the die temperature exceeds t he maximum safe operating temperature. transient protection allows device survival even when the input voltage spikes above and below nominal. the output structure of these regulators allows voltages in excess of the desired output voltage to be applied wi thout reverse current flow. output capacitor requirement the ts3930 0/1/2/3 requires an output capacitor to maintain stability and improve transient response is necessary. the value of this capacitor is dependent upon the output current, lower currents allo w smaller capacitors. ts3930 0/1/2/3 output capacitor selection is dependent upon the esr of the output capacitor to maintain stability. when the output capacitor is 10uf or greater, the output capacitor should have an esr less than 2 . this will improve tr ansient response as well as promote stability. ultra low esr capacitors (<100m ), such as ceramic chip capacitors, may promote instability. these very low esr levels may cause an oscillation and/or under damped transient response. a low esr solid tantalum capacitor works extremely well and provides good transient response and stability over temperature aluminum electrolytes can also be used, as long as the esr of the capacitor is <2 . the value of the output capacitor can be increased without limit. higher capacitance values help to improve transient response and ripple rejection and reduce output noise. input capacitor requirement an input capacitor of 1uf or greater is recommended when the device is more than 4 away from the bulk ac supply capacitance or when the supply is a battery. small, surface mount, ceramic chip capacitors can be used for bypassing. larger values will help to improve ripple rejection by bypassing the input to the regulator, further improving the integrity of the output voltage. mini mum load current the ts3930 0/1/2/3 is specified between finite loads. if the output current is too small leakage currents dominate and the output voltage rises. a 10ma minimum load current is necessary for proper regulation. adjustable regulator design the adjustable regulator versions (ts39302) is allow to programming the output voltage anywhere between 1.25 and the 16v maximum operating rating of the family. two resistors are used. resistors can be quite large up to 1m , because of the very high input impedance and low bias current of the sense comparator, the resistor values are calculated by: where v out is the desired output voltage. above application circuit shows component definition. applications with widely var ying load currents may scale the resistors to draw the minimum load current required for proper operation.
ts39300/1/2/3 3a ultra low dropout voltage regulator with multi - f unction 6 / 12 version: b07 application information (continue) enable input ts39301/2/3 versions feature an active - high enable (en) input that allows on/off control of the regu lator. current drain reduces to zero when the device is shutdown, with only micro - amperes of leakage current. the en input has ttl/cmos compatible thresholds for simple interfacing with logic interfacing. en may be directly tied to v in and pulled up to t he maximum supply voltage. error flag ts39301 versions feature an error flag, which looks at the output voltage and signals an error condition when this voltage drops 5% below its expected value. the error flag is an open - collector output that pulls low u nder fault conditions. it may sink 10ma. low output voltage signifies a number of possible problems, including an over - current fault (the device is in current limit) or low input voltage. the flag output is inoperative during over temperature shutdown cond itions. a pull - up resistor from error flag to either v in or v out is required for proper operation. for information regarding the minimum and maximum values of pull - up resistance, refer the graph as follow: transient response and 3.3v to 2.5v or 2.5v to 1.8v conversion ts39300/1/2/3 has excellent transient response to variations in input voltage and load current . the device have been designed to respond quickly to load current variations and input voltage variations. large output capacitors are not required to obtain this performance. a standard 10uf output capacitor, preferably tantalum, is all that is required. larger values help to improve performance even further. by virtue of its low dropout voltage, this device does not saturate into dropo ut as readily as similar npn base designs. when converting from 3.3v to 2.5v or 2.5v to 1.8v, the npn based regulators are already operating in dropout, with typical dropout requirements of 1.2v or greater,. to convert down to 2.5v or 1.8v without operatin g in dropout, npn based regulators require an input voltage of 3.7v at the very least. the ts39300/1/2/3 regulator will provide excellent performance with an input as low as 3.0v or 2.5v respectively. this gives the pnp based regulators a distinct advan tage over older, npn based linear regulators. output sense sense pin can be connect ed to the load and tr aces the load voltage, ts39303 will adjust the output voltage to maintain the load at expected voltage.
ts39300/1/2/3 3a ultra low dropout voltage regulator with multi - f unction 7 / 12 version: b07 application information (continue) thermal c haracteristics ts39300/1/2/3 linear regulators are simple to use, the most complicated design parameters to consider are thermal characteristics, thermal design requires the following application specification parameters: ? maximum ambient temperature , t a ? o utput current, i out ? output voltage, v out ? input voltage, v in calculate the power dissipation of the regulator from these numbers and the device parameters from this datasheet, where the ground current is taken from data sheet. p d = (v in v out ) x i out + v in x i gnd the heat sink thermal resistance is determined by: ? sa = (t j(max) t a ) / p d ( ? jc + ? cs ) where t j(max) 125 o c and ? cs is between 0 o c and 2 o c /w. the heat sink may by significantly reduced in applications where the minimum input voltage is know an d is large compared with the dropout voltage and distribute the heat between this resistor and the regulator. the low dropout properties of vertical pnp regulators allow significant reductions in regulator power dissipation and the associated heat sink wit hout compromising performance. when this technique is employed, a capacitor of at least 1 u f is needed directly between the input and regulator ground. typical application circuit 2.5v/3a regulator 2.5v/3a regulator with error flag
