♠ LP2985 150-mA, Haruru-Hangai, Kaiwhakarite Whakataka-iti me te Whakaweto
Ko te LP2985 he putunga-putanga, whanui-whakauru, iti-haruru, iti-maturuturu ngaohiko ngaohiko e tautoko ana i te awhe ngaohiko whakauru mai i te 2.5 V ki te 16 V tae atu ki te 150 mA o te kawenga o naianei.E tautoko ana te LP2985 i te awhe whakaputanga 1.2 V ki te 5.0 V (mo te maramara hou).
I tua atu, ko te LP2985 (maramarama hou) he 1% te tika o te whakaputa puta noa i te kawenga, me te pāmahana e taea ai te whakatutuki i nga hiahia o nga microcontrollers iti-ngaohiko (MCU) me nga kaitukatuka.
He iti te haruru putanga o te 30 µVRMS (me te 10-nF maataki punga hiko) me te whanui whanui PSRR mahi nui ake i te 70 dB i te 1 kHz me te 40 dB i te 1 MHz ka awhina i te whakaiti i te auau whakawhiti o te kaitahuri DC/DC whakarunga me te whakaiti i te tātari pou whakahaere. .
Ko te wa timatanga-ngohengohe o roto me te whakamarumaru tepe o naianei ka whakaiti i te kokiritanga o naianei i te tiimatanga, na reira ka whakaiti i te kaha whakauru.Ko nga ahuatanga whakamarumaru paerewa, penei i te whakamarumaru o te overcurrent me te whakamarumaru wera nui, kei roto.
Kei te waatea te LP2985 i roto i te kete 5-pin 2.9-mm × 1.6-mm SOT-23 (DBV).
