♠ LP2985 150-mA, Phokoso Lapansi, Low-Dropout Regulator Ndi Shutdown
LP2985 ndi chowongolera chokhazikika, chowonjezera, chaphokoso chotsika, chowongolera ma voltage otsika omwe amathandizira ma voliyumu olowera kuchokera pa 2.5 V mpaka 16 V mpaka 150 mA ya katundu wapano. LP2985 imathandizira kutulutsa kwa 1.2 V mpaka 5.0 V (kwa chip chatsopano).
Kuphatikiza apo, LP2985 (chip yatsopano) ili ndi kulondola kwa 1% podutsa katundu, ndi kutentha komwe kumatha kukwaniritsa zosowa za ma microcontrollers otsika kwambiri (MCUs) ndi mapurosesa.
Phokoso lotsika la 30 µVRMS (lokhala ndi 10-nF bypass capacitor) komanso bandwidth yokulirapo ya PSRR magwiridwe antchito opitilira 70 dB pa 1 kHz ndi 40 dB pa 1 MHz amathandizira kuchepetsa kusinthasintha kwa chosinthira cham'mwamba cha DC/DC ndikuchepetsa kusefa koyang'anira positi.
Nthawi yoyambira yofewa yamkati ndi chitetezo cha malire apano chimachepetsa kuthamangitsidwa panthawi yoyambira, motero kumachepetsa mphamvu yolowera. Zinthu zodzitchinjiriza zokhazikika, monga chitetezo chambiri komanso kutentha kwambiri, zikuphatikizidwa.
LP2985 ikupezeka mu phukusi la 5-pin 2.9-mm × 1.6-mm SOT-23 (DBV).
