NR1620 Series
150mA 0.4V Output & Ultra-Low Supply Current Voltage Regulator
-
Description
The NR1620 series are a voltage regulator manufactured using a CMOS process with the output current of 150 mA.
This device supports the VIN input voltage as low as 0.6 V and the output voltage as low as 0.4 V. This device can be used as a power supply for the core of a microcontroller, various interfaces, etc.
In addition, the ultra-low quiescent current of 0.4 μA makes it suitable to use in systems that require low consumption and long time operation, such as battery-driven systems.
NMOS power transistors are driven by a bias power input pin (VBIAS) independent of the power input pin (VIN) to achieve highly efficient regulation.
