Toshiba-TCR3RMxxA-LDO

Kunemikhiqizo engama-32 ochungechungeni lwe-TCR3RM, njengoba kuzokwaziwa, ngemiphumela eyodwa engaguquki ehlanganisa u-0.9 kuye ku-4.5V.

Isilinganiselo sokwenqatshwa kwe-Ripple ngokujwayelekile siyi-100dB (1kHz, 2.8V okukhipha okuhlukile), futhi inesici semvamisa esenzelwe abaguquli be-dc-dc abathumela emuva kokulawula.

"Ngokungafani nezinye izilawuli ze-LDO lapho isilinganiso sokunqatshelwa kwe-ripple kuvame ukwehla ama-dB angama-20 njalo ukwanda okuphindwe kayishumi, i-TCR3RM yehla kakhulu," ngokusho kwenkampani. "Isilinganiso sokunqatshwa ku-1MHz [okukhipha okungu-2.8V] singu-68dB."


Ukusebenza komsindo nokuxokozela, kusho uToshiba, kungenxa yokwakhiwa kwesekethe yangaphakathi ye-bandgap, isihlungi sephasi eliphansi kanye ne-amplifier esebenza ngejubane eliphansi.

Ama-capacitors wokufaka nokukhipha we-1μF ayadingeka, okungaba izinhlobo ze-ceramic.

Isilinganiso samanje sokukhipha esingu-300mA namandla okuphuma ngokweqile ngokujwayelekile yi-130mV ekhipha i-2.8V ku-300mA.

I-Quiescent yamanje ingu-12μA max kububanzi obusebenzayo obungu -40 kuye ku-85 ° C.

Iphini yokulawula ivula futhi icime okukhiphayo (high = kuvuliwe, low = off, open = off). I-transistor yangaphakathi ikhipha ngokuzenzakalela amandla wokukhipha lapho okukhiphayo kuvaliwe. Ema-stand-up, i-max yamanje esetshenziswe ngaphesheya kwe-temperatre yi-1μA (100nA typ 25 ° C)

Ezinye izici zifaka phakathi ukuvikelwa okwedlulele nokuvalwa okushisayo.

Izicelo zibonwa kusengaphambili kumadivayisi aphathekayo futhi agqokekayo, njengokuzwa, imikhiqizo ye-RF ne-IoT.
