tc1188/tc1189 ds21364b-page 6 2002 microchip technology inc. 3.0 pin descriptions the descriptions of the pins are listed in table 3-1. table 3-1: pin function table 3.1 detailed description the tc1188/tc1189 devices are fixed output, low dropout linear regulators. utilizing cmos construction, the internal quiescent current consumed by the regula- tor is minimized when compared to older bipolar low dropout regulators. the ldo output voltage is sensed at the non-inverting pin of the internal error amplifier. the internal voltage reference is sensed at the inverting pin of the internal error amplifier. the error amplifier adjusts the gate source voltage of the internal p-channel pass device until the divided down output voltage matches the inter- nal reference voltage. when it does, the ldo output voltage is in regulation. the shdn, when pulled low, is used to turn off the p- channel mosfet and lower the internal quiescent current to less than 1 a maximum. for normal opera- tion, the shdn pin is pulled to a high level. (> 2.0v). the tc1189 incorporates an internal n-channel mos- fet, which is used to discharge the output capacitor when shutdown. the tc1188 does not have the inter- nal n-channel mosfet, therefore, when the device is shutdown, the output voltage will decrease at a rate which is dependant on the load current. 3.2 turn-on response the turn-on response is defined as two separate response categories: wake-up time (t wk ) and settling time (t s ). the tc1188/tc1189 have fast wake-up times (10 sec typical) when released from shutdown. see figure 3-1 for the wake-up time, designated as t wk . the wake-up time is defined as the time it takes for the output to rise to 2% of the v out value after being released from shut- down. the total turn on response is defined as the settling time (t s ) (figure 3-1). settling time (inclusive with t wk ) is defined as the condition when the output is within 2% of its fully enabled value (140 sec typical) when released from shutdown. the settling time of the output voltage is dependent on load conditions and output capacitance on v out (rc response). figure 3-1: wake-up response time. 3.3 internal p-channel pass transistor the internal p-channel mosfet is operated in the lin- ear region to regulate the ldo output voltage. the rdson of the p-channel mosfet is approximately 1.1 , making the ldo able to regulate with little input to output voltage differential, "low dropout". another benefit of using cmos construction is that the p-chan- nel mosfet is a voltage controlled device, so it doesn't consume a fraction of the bias current required of bipolar pnp ldos. symbol description shdn active low shutdown input. when the shdn input is low (< 0.2v), the quiscent current for the tc1188/tc1189 is reduced to 0.1 na. when the input voltage to the s hdn pin is high (> 2.0v) the output of the tc1188/tc1189 is enabled. for the tc1189 only, the output capacitor is discharged by an internal switch when the shdn is low. gnd ground. connect to ground. v in unregulated input voltage. the input voltage can range from 2.7v to 6.0v. v out regulator output. sources up to 120 ma. bypass with a 1 f, <1 typical esr capacitor to gnd. gnd connect to gnd. v ih t s t wk v out 98% 2% v il shdn

tc1188/tc1189 ds21364b-page 8 ? 2002 microchip technology inc. example 3-1: the previously defined power dissipation equations can be used to ensure that the regulator thermal operation is within limits. given: v in(max) = 3.0v +10% v out(max) = 2.7v - 2.5% i load(max) = 40 m a t j(max) = 125c t a(max) = 55c find: 1. actual power dissipation. 2. maximum allowable dissipation. actual power dissipation: maximum allowable power dissipation: in this example, the tc1188/tc1189 dissipates a max- imum of 26.7 mw below the allowable limit of 318 mw. in a similar manner, the power dissipation equation, as a function of v in , v out and i load, along with the power dissipation equation, as a function of maximum junction temperature, maximum ambient temperature and junc- tion to air thermal resistance, can be used to calculate maximum current and/or maximum input voltage limits. 4.0 applications information 4.1 input capacitor a 1 f (or larger) capacitor is recommended to bypass the ldo input and lower input impedance for circuit stability when operating from batteries or high imped- ance sources. the input capacitor can be ceramic, tan- talum or aluminum electrolytic. for applications that require low noise and input power supply rejection, low effective series resistance (esr) ceramic capacitors are recommended over higher esr electrolytic capac- itors. larger value input capacitors can be used to improve circuit performance. 4.2 output capacitor a 1 f (minimum) capacitor is required from v out to ground to ensure circuit stability. the output capacitor should have an esr greater than 0.1 ohms and less than 2 ohm. tantalum or aluminum electrolytic capaci- tors are recommended. since many aluminum electro- lytic capacitors freeze at approximately -30c, solid tantalums are recommended for applications operating below 25c. p d = v in(max) - v out(min) x i load(max) p d = ((3.0 * 1.1) - (2.7 * 0.975)) * 40 ma p d = 26.7 mwatts p d = (t j(max) - t a(max) )/ ja p d(max) = (125 - 55) / 220 p d(max) = 318 mwatts.
