NR1600 series 500mA Low Dropout Voltage Regulator with Soft-Start Time Adjustment and Power-Good Function
2023-06-05
●GENERAL DESCRIPTION
■The NR1600 series are CMOS-based low dropout voltage regulator with Soft-start function and Power- Good function.
■An external capacitor (CSS) can be used to adjust the Soft-start time during startup, making it easy to suppress inrush current and adjust slew rate. In addition, although it is a 500mA regulator with Soft- start and Power-Good function, it has a lineup of small packages of 1.2mm x 1.2mm x 0.4mm, which contributes to system space saving.
●FEATURES
■Input Voltage Range (Maximum Rating): 1.4 V to 5.5 V (6.5 V)
■Output Voltage Range:
▲Fixed Output Voltage Type: 1.0 V to 3.6 V
▲Adjustable Output Voltage Type: 1.0 V to 4.8 V
■Output Current: 500 mA
■Quiescent Current: Typ. 80 μA
■Output Noise Voltage:
▲Typ. VSET × 30 μVrms (IOUT = 100 mA)
■Ripple Rejection: Typ. 75 dB (f = 1 kHz)
■Dropout Voltage: Typ. 0.16 V (IOUT = 500 mA, VSET = 3.3 V)
■Thermal Shutdown Function: Typ. 165°C
■Start-Up Inrush Current Limit: Typ. 160 mA
■Foldback Protection
■Soft-Start Time Adjustment Function (CSS adjustment), Power-Good Function, Discharge Function
