| NJW4180 High Voltage Low current consumption Regulator GENERAL DESCRIPTION The NJW4180 is a high voltage and low current consumption linear regulator. Low current consumption make the NJW4180 possible to supply 2.5 to 5.0 V regulated voltage from high voltage input. Therefore, it is suitable for a power supply for micro controllers, battery related applications, LED and other applications where low power consumption is essential.

Use the CIN value of 0.1F greater to avoid the problem. CIN should connect between GND and VIN as short as possible. *Output Capacitance CO Output capacitor (CO) is required for a phase compensation of the internal error amplifier. The capacitance and the equivalent series resistance (ESR) influences stability of the regulator. This product is designed to work with a low ESR capacitor for the CO; however, use of recommended capacitance or greater value is essential for stable operation. Use of a smaller CO may cause excess output noise or oscillation of the regulator due to lack of the phase compensation. Therefore, use CO with the recommended capacitance or greater value and connect between VO terminal and GND terminal with minimal wiring. The recommended capacitance depends on the output voltage. Low voltage regulator requires greater value of the CO. Thus, check the recommended capacitance for each output voltage. Use of a greater CO reduces output noise and ripple output, and also improves transient response of the output voltage against rapid load change.
