ON NCP4681DSQ33T1G

Позитив5.25V150 мА

Overview

The NCP4681DSQ33T1G and NCP4684 are CMOS Linear voltage regulators with 150 mA output current capability and ultra low supply currents (1 A typ.) The devices are easy to use and include output current protection and a fully integrated soft−start circuit to minimize inrush current and to ensure no output voltage overshoot. The NCP4681DSQ33T1G includes an Enable function to reduce supply current by using a Standby mode, while the NCP4684 excludes the Enable pin to avoid any pull down current, thereby offering the lowest possible current consumption for battery powered applications in Active mode. For portable products the devices are available in the exceptionally small 0.8 x 0.8 mm XDFN, along with the SC−70 and SOT23 packages

• Operating Input Voltage Range: 1.40 V to 5.25 V• Output Voltage Range: 0.8 V to 3.6 V (available in 0.1 V steps)• Output Voltage Accuracy: ±1.0%• Supply Current: 1 μA (excluding the CE pull down current)• Dropout Voltage: 0.28 V (IOUT = 150 mA, VOUT = 2.8 V)• Line Regulation: 0.02%/V Typ.• Stable with Ceramic Capacitors: 0.1 F or more• Current Fold Back Protection• Build−in Constant Slope Circuit for soft−start function• Available in XDFN4 0.8 x 0.8 mm, SC−70, SOT23 Packages• These are Pb−Free Devices
