11-20-94 TK114XX january, 1995 toko, inc. page 1 features n low dropout voltage n electronic on/off switch n very low standby current (on, no load) n internal thermal shutdown n short circuit protection n very low (<100 na) current in off mode n customized versions are available description the TK114XX is a low power, linear regulator with a built- in electronic switch. the internal electronic switch can be controlled by an external pull-up resistor and an open drain or open collector transistor. the device is in the off state when the control pin is biased from v in through the pull-up resistor. an internal pnp pass-transistor is used in order to achieve low dropout voltage (typically 200 mv at 50 ma load current). the device has very low quiescent current (500 m a) in the on mode with no load and 2 ma with 30 ma load. the quiescent current is typically 4 ma at 60 ma load. an internal thermal shutdown circuit limits the junction tem- perature to below 150 c. the load current is internally monitored and the device will shut down (no load current) in the presence of a short circuit at the output. the device is available in a small sot-23l surface mount package. voltage regulator with on/off switch applications n battery powered systems n cellular telephones n pagers n personal communications equipment n portable instrumentation n portable consumer equipment n radio control systems n toys n low voltage systems block diagram 1 3 control gnd 6 4 v in v o kt114xxm.po 2 5 TK114XXm tk114 voltage code tape/reel code tape/reel code bx : bulk/bag tl : tape left ordering information voltage code 30 = 3.0 v 32 = 3.25 v 35 = 3.5 v 37 = 3.75 v 40 = 4.0 v 45 = 4.5 v 47 = 4.75 v 50 = 5.0 v 55 = 5.5 v 57 = 5.75 v 60 = 6.0 v 80 = 8.0 v s s s s s s s s s s v o v in low control (lc) gnd kt114xx ?bd TK114XX bandgap reference + high control (hc) + s s s s thermal protection s s 2 1 3 6 8 r3

TK114XX 11-20-94 page 22 january, 1995 toko, inc. handling molded resin packages all plastic molded packages absorb some moisture from the air. if moisture absorption occurs prior to soldering the device into the printed circuit board, increased separation of the lead from the plastic molding may occur, degrading the moisture barrier characteristics of the device. this property of plastic molding compounds should not be overlooked, particularly in the case of very small packages, where the plastic is very thin. application hints maximize copper foil area connecting to all ic pins for optimum performance. place input and output bypass capacitors close to the gnd pin. for best transient behav- ior and lowest output impedance, use as large a capacitor value as possible. the temperature coefficient of the ca- pacitance and equivalent series resistance (esr) should be taken into account. these parameters can influence power supply noise and ripple rejection. in extreme cases, oscillation may occur. in order to maintain stability, the output bypass capacitor value should be minimum 2.2 m f for a tantalum electrolytic or 4.7 m f for an aluminum electrolytic. in order to preserve the original moisture barrier properties of the package, devices are stored and shipped in moisture proof bags, filled with dry air. the bags should not be opened or damaged prior to the actual use of the devices. if this is unavoidable, the devices should be stored in a low relative humidity environment (40 to 65%) or in an enclosed environment with desiccant. printed circuit board layout note: parallel connection of control pins is allowed if all devices use identical input voltage. control function utilized control function not utilized ta01 v in s s s v o 1 f m 4.7 f m r = 100k max w s s pull-up resistor rmax/n devices + + s (see note) (optional) to other TK114XX devices on/off control 1 2 3 4 5 6 typical applications s s s s out 10 f m 100k in tc02 TK114XX + 0.95 mm kt114xx ?pcbl01 + + gnd scale: 10:1
