ADM7170ACPZ-3.3 LDO Voltage Regulators 0.5A Hi PSRR FT LDO 3.3Vo

ADM7170 ke CMOS, low dropout linear regulator (LDO) e sebetsang ho tloha ho 2.3 V ho ea ho 6.5 V mme e fana ka ho fihlela ho 500 mA ea tlhahiso ea hona joale. LDO ena e phahameng ea hona joale e nepahetse bakeng sa taolo ea li-analog tse phahameng tsa ts'ebetso le li-circuits tse tsoakiloeng tse sebetsang ho tloha ho 6 V ho ea ho 1.2 V rails. U sebelisa meralo e tsoetseng pele ea thepa, sesebelisoa se fana ka ho hana phepelo ea matla a phahameng le lerata le tlase, 'me se fihlella mohala o motle le karabelo ea nakoana ka 4.7 µF ceramic output capacitor e nyane feela. Karabelo ea nakoana ea mojaro hangata ke 1.5 μs bakeng sa 1 mA
ho 500 mA mohato oa mojaro.

ADM7170 e fumaneha ka likhetho tse 17 tse tsitsitseng tsa motlakase. Li-voltages tse latelang li fumaneha ho tloha setokong: 1.3 V, 1.8 V, 2.5 V, 3.0 V, 3.3 V, 4.2 V, le 5.0 V. Lisebelisoa tse eketsehileng tse fumanehang ka taelo e khethehileng ke: 1.5 V, 1.85 V, 2.0 V, 2.2 V, 2.5 V, 2.8 V, 2.8 V, 2.8 V, 2.8 V, 2. 3.8 V, le 4.6 V. Phetolelo e feto-fetohang e boetse e fumaneha e lumellang li-voltage tse tsoang ho tloha ho 1.2 V ho ea ho VIN - VDO e nang le karohano ea ka ntle ea maikutlo.

Inrush current e ka laoloa ka ho fetola nako ea ho qala ka phini e bonolo ea ho qala. Nako e tloaelehileng ea ho qala ka 1 nF soft start capacitor e ka ba 1.0 ms.

ADM7170 regulator output lerata ke 5 μV rms e ikemetseng ho motlakase oa tlhahiso. ADM7170 e fumaneha ka 8-lead, 3 mm × 3 mm LFCSP, e etsang hore e se ke ea e-ba tharollo e fokolang haholo, empa hape e fana ka ts'ebetso e babatsehang ea mocheso bakeng sa likopo tse hlokang ho fihla ho 500 mA ea tlhahiso ea hona joale sebakeng se senyenyane, se tlaase.
