Batsamaisi ba TPS780 ba lelapa la low-dropout (LDO) ba fana ka melemo ea matla a tlase haholo, sephutheloana sa miniaturized, le maemo a ka khethoang a mekhahlelo e 'meli ea motlakase ka V.HLOKOMELApin.
Matla a tlase haholo le a dynamic voltage scaling (DVS) a fanang ka li-voltage tsa mekhahlelo e 'meli e lumella baqapi hore ba hlophise tšebeliso ea matla bakeng sa lits'ebetso tse ikhethileng.Hona joale baqapi ba ka fetohela boemong bo tlase ba motlakase ka moralo o tsamaisoang ke betri ha microprocessor e le maemong a ho robala, e leng ho fokotsang tšebeliso ea matla a sistimi ka kakaretso.Maemo a mabeli a motlakase a setiloe esale pele fekthering 'me a bolokoa ho sebelisoa EPROM' me a fumaneha lisebelisoa tsa motlakase tse tsitsitseng.
Letoto la TPS780 la LDO li etselitsoe ho lumellana le TI MSP430 le lihlahisoa tse ling tse tšoanang.Pini ea ho nolofalletsa e lumellana le logic e tloaelehileng ea CMOS.Letoto la TPS780 le boetse le tla le ho koala ha mocheso le moeli oa hajoale ho sireletsa sesebelisoa nakong ea maemo a phoso.Liphutheloana tsohle li na le mocheso o sebetsang oa TJ= -40°C ho isa ho 125°C.Bakeng sa lits'ebetso tse baballang litšenyehelo tse ngata tse hlokang khetho ea "voltage ea maemo a mabeli" 'me ke feela ka karolo ea IQ, nahana ka letoto la TPS781, le IQea 1.0 µA le sekala sa motlakase o matla.
