♠ I-LP2985 150-mA, Isilawuli Somsindo Ophansi, Isilawuli Sokudonsela Phansi Ngokuvala
I-LP2985 iwukukhipha okungaguquki, okokufaka okubanzi, umsindo ophansi, isilawuli samandla kagesi aphuma kancane esisekela ububanzi bamandla okufakwayo ukusuka ku-2.5 V kuya ku-16 V futhi kufika ku-150 mA womthwalo wamanje. I-LP2985 isekela ububanzi bokuphuma kuka-1.2 V ukuya ku-5.0 V (ku-chip entsha).
Ukwengeza, i-LP2985 (i-chip entsha) inokunemba kokuphumayo okungu-1% kuwo wonke umthwalo, nezinga lokushisa elingahlangabezana nezidingo zama-microcontrollers (MCUs) nama-processor amancane.
Umsindo ophansi wokukhiphayo ongu-30 µVRMS (onama-bypass capacitor angu-10-nF) kanye nokusebenza komkhawulokudonsa obanzi we-PSRR okukhulu kuno-70 dB ku-1 kHz no-40 dB ku-1 MHz kusiza ukunciphisa imvamisa yokushintsha kwesiguquli se-DC/DC esikhuphuka nomfula futhi sinciphise ukuhlunga kwesilawuli sokuthunyelwe.
Isikhathi sangaphakathi sokuqalisa okuthambile kanye nokuvikelwa komkhawulo wamanje kunciphisa ukungena ngaphakathi ngesikhathi sokuqalisa, ngaleyo ndlela kunciphisa amandla okufaka. Izici zokuvikela ezijwayelekile, ezifana nokuvikela i-overcurrent kanye nezinga lokushisa elingaphezulu, zifakiwe.
I-LP2985 itholakala kuphakheji engu-5-pin 2.9-mm × 1.6-mm SOT-23 (DBV).
• Ibanga le-VIN (i-chip entsha): 2.5 V kuya ku-16 V
