LDO & Voltage Regulators | NCP737
概览
The NCP737 is a high-voltage tolerant linear regulator that offers the benefits of thermally enhanced MSOP8 EP and DFNW8 3x3 (on request) packages and is able to withstand continuous DC or transient input voltages up to 65 V with Ultra-low Quiescent Current below 5 uA. The device is stable with small 1 uF Ceramic Output Capacitors which allows smaller PCB design. The devices features enable pin compatible with standard CMOS logic, internal power good circuit with a user programmable delay via external capacitor. The active high output of power good has open drain with internal current limitation.
