♠ LP2985 150-mA, ingxolo ephantsi, i-Low-Dropout Regulator kunye nokuvalwa
I-LP2985 yi-fixed-output, i-wide-input, isandi esiphantsi, i-low-dropout voltage regulator exhasa i-votage input range ukusuka kwi-2.5 V ukuya kwi-16 V ukuya kwi-150 mA yomthwalo wangoku. I-LP2985 isekela uluhlu lwemveliso ye-1.2 V ukuya kwi-5.0 V (kwi-chip entsha).
Ukongezelela, i-LP2985 (i-chip entsha) ine-1% yokuchaneka kwemveliso kuwo wonke umthwalo, kunye neqondo lokushisa elinokuthi lihlangabezane neemfuno ze-micro-voltage microcontrollers (MCUs) kunye neeprosesa.
Ingxolo esezantsi ephumayo ye-30 µVRMS (ene-10-nF bypass capacitors) kunye nobubanzi bokusebenza kwe-PSRR yobubanzi obungaphezulu kwe-70 dB kwi-1 kHz kunye ne-40 dB kwi-1 MHz inceda ukuthomalalisa ukujika kokutshintsha kwesiguquli esinyukayo se-DC/DC kunye nokunciphisa ukuhluzwa kwesilawuli seposi.
Ixesha lokuqalisa elithambileyo langaphakathi kunye nokukhuselwa komda wangoku kunciphisa i-inrush yangoku ngexesha lokuqalisa, oko kunciphisa amandla okufaka. Iimpawu zokukhusela ezisemgangathweni, ezifana nokukhuselwa kwe-overcurrent kunye ne-overtemperature, zibandakanyiwe.
I-LP2985 ifumaneka kwi-5-pin 2.9-mm × 1.6-mm SOT-23 (DBV) iphakheji.
• Uluhlu lwe-VIN (i-chip entsha): 2.5 V ukuya kwi-16 V
