NCP737 Linear Regulators

onsemi regulators feature a built-in soft start circuit to suppress inrush current

Image of onsemi NCP737 Linear RegulatorThe onsemi NCP737 is a high-voltage-tolerant linear regulator that offers the benefits of thermally enhanced MSOP8-EP and DFNW8 3 x 3 (on request) packages. It is able to withstand continuous DC or transient input voltages up to 65 V with ultra-low quiescent current below 5 µA. The device is stable with small 1 µF ceramic output capacitors, allowing for a smaller PCB design. The devices are pin compatible with standard CMOS logic and also feature an internal power good circuit with a user-programmable delay via an external capacitor. The active high output of power good has an open drain with internal current limitation.
