300mA phokoso lochepa LDO ndi 1 x 1mm

300mA phokoso lochepa LDO ndi 1 x 1mm

2020-11-26
Toshiba-TCR3RMxxA-LDO

Pali zinthu 32 pamndandanda wa TCR3RM, monga udzadziwika, ndi zotuluka zosasunthika zomwe zimayambira 0.9 mpaka 4.5V.

Chiŵerengero chokana Ripple nthawi zambiri chimakhala 100dB (1kHz, 2.8V zotulutsa zosiyanasiyana), ndipo chimakhala ndi mawonekedwe amakulitsidwe opitilira otembenuza DC-DC posintha.

"Mosiyana ndi oyang'anira ena a LDO pomwe kuchuluka kwa kukana kwamphamvu nthawi zambiri kumatsika 20 dB kuwonjezeka konse kawiri, TCR3RM imagwa pang'ono," malinga ndi kampaniyo. "Kuchuluka kwa kukanidwa pa 1MHz [kutulutsa kwa 2.8V] ndi 68dB."


Magwiridwe antchito ndi phokoso, atero Toshiba, chifukwa cha kapangidwe ka bandgap yoyenda mkati, fyuluta yotsika komanso chopukutira chothamanga kwambiri.

1μF kulowetsa ndi kutulutsa ma capacitors amafunikira, omwe atha kukhala mitundu ya ceramic.

Kutulutsa kochuluka kwaposachedwa ndi 300mA ndi kutuluka kwamagetsi nthawi zambiri kumakhala 130mV yotulutsa 2.8V pa 300mA.

Quiescent yaposachedwa ndi 12μA max pamtunda wonse wa -40 mpaka 85 ° C.

Pini yolamulira imatsegula ndikuzimitsa (high = on, low = off, open = off). Transistor yamkati imangotulutsa zokha pokhapokha ngati kutulutsa kwazimitsidwa. Poyimirira, ma max omwe amadya modutsa temperatre ndi 1μA (100nA typ 25 ° C)

Zina mwazinthu ndizopitilira pano komanso kutseka kwamatenthedwe.

Mapulogalamuwa amawonekeratu pazida zotheka komanso zowoneka bwino, monga kuzindikira, RF ndi IoT.

Tsamba lazidziwitso lili pano
