p i n s h o r t s a n d m o u n t i n g e r r o r s use caution when orienting and positioning the ic for mounting on printed circuit boards. improper m ounting or shorts between pins may result in damage to the ic. 5.) o p e r a t i o n i n s t r o n g e l e c t r o m a g n e t i c f i e l d s strong electromagnetic fields may cause the ic to malfunction. caution should be exercised in applic ations where strong electromagnetic fields may be present. 6.) c o m m o n i m p e d a n c e wiring traces should be as short and wide as possible to minimi ze common im pedance. bypass capacitors should be use to keep ripple to a minimum. 7.) v o l t a g e o f s t b y p i n to enable standby mode for all channels, set the stby pin to 0.3 v or less, and for normal ope ration, to 1.2 v or more. setting stby to a voltage between 0.3 and 1.2 v may cause malfunction and should be avoided. keep transitio n time between high and low (or vice versa) to a minimum. additionally, if stby is shorted to vin, the ic will switch to standby mode and disable the output discharge circuit, causing a temporary voltage to remain on the output pin. if the ic is switched on again while this voltage is pr esent, overshoot may occur on the output. therefore, in applications where these pins are shorted, the output should alw ays be completely discharg ed before turning the ic on. 8.) o v e r - c u r r e n t p r o t e c t i o n c i r c u i t ( o c p ) this ic features an integrated over-current and short-protection circuitry on the output to prevent destruction of the ic when the output is shorted. the ocp circuitry is designed only to protect the ic from irregular conditio ns (such as motor output shorts) and is not designed to be used as an active security device for the application. therefore, applications should not be designed under the assumption that this circuitry will engag e. 9.) t h e r m a l s h u t d o w n c i r c u i t ( t s d ) this ic also features a thermal shutdown circuit that is design ed to turn the output off when the junctio n temperature of the ic exceeds about 150. this feature is intended to protect the ic only in the even t of thermal ove rload and is not designed to guarantee operation or act as an active security device for the application. therefore, applicat ions should not be designe d under the assumption that this circuitry will engage. 10.) i n p u t / o u t p u t c a p a c i t o r capacitors must be connected between the input/output pins and gnd for stable operation, and should be physically mounted as close to the ic pins as possible. the input capacitor helps to counteract increases in power supply impedance, and increases stability in applications with long or winding power supply traces. the output capacitance value is directly related to the overall stability and transient response of the regulator, and should be set to the largest possible value for the application to increase these characteristics. during design, keep in mind that in general, ceramic capacitors h ave a wide range of tolerances, temperature coefficients and dc bias characteristics, and that their capacitance values tend to decr ease over time. confirm these details before choosing appropriate capacitors for your a pplicatio n.(please refer the technic al note, regard ing ceramic capacitor of recommendation) 11.) a b o u t t h e e q u i v a l e n t s e r i e s r e s i s t a n c e ( e s r ) o f a c e r a m i c c a p a c i t o r capacitors generally have esr (equivalent series resistance) and it operates stably in the esr-iout area shown on the right. since ceramic capacitors, tantalum capacitors, electrolytic capacitors, etc. generally have different esr, please check the esr of the capacitor to be used and use it within the stability area range shown in the right graph for evaluation of the actual application. fig. 286 stable region (example) unstable region 0.01 0.1 1 10 100 0 50 100 150 200 iout [ma] esr [ ? ] [] = = = downloaded from: http:/// www.rohm.com ? 2013 rohm co., ltd. all rights reserved. tsz02201-0rbr0a300050-1-2 tsz22111 ? 15 ? 001 40/40 14.jan.2013.rev.008 buxxtd2wnvx series datasheet revision history date revision changes 7.feb.2013 001 new release. 15.mar.2013 002 adding reference data. adding a revision history. 24.apr.2013 003 adding 1.3v product. 31.jul.2013 004 adding dropout voltage. delete electrical characteristics of each output voltage. vsbyh is changed. 21.aug.2013 005 adding dropout voltage. 28.aug.2013 006 ordering information is changed. 24.oct.2013 007 adding pin descriptions. adding bottom view. 14.jan.2014 008 adding 1.1v product downloaded from: http:/// datasheet d a t a s h e e t notice -
