NR1620 series 150 mA 0.4 V Output & Ultra-Low Supply Current Voltage Regulator Datasheet
2024-04-17
●GENERAL 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.
●FEATURES
■Quiescent Current: Typ. 0.4 μA
■Output Voltage Accuracy: ±9.9 mV (Ta = 25℃)
■Input Voltage Range (Maximum rating):

▲Typ. 60 dB (f = 100 kHz, Ripple in VIN)
■Dropout Voltage : Typ. 150 mV (IOUT =150 mA,VSET=1.0 V,VBIAS=VSET+1.4 V)
■Short-Circuit Current Limit: Typ. 110 mA
■Ceramic Capacitors Supported:
▲CIN, CBIAS, COUT
▲COUT: 2.2 μF to 100 μF
■Operation Mode: automatic mode switching (fast mode , low power mode)
■Output Current: 150 mA
■Discharge Function selectable
