NCP59800 Voltage Regulator - Low Noise, RF LDO 1 A The NCP59800 is a 1 A low dropout linear regulators (LDOs) www.onsemi.com offering high power supply ripple rejection (PSRR) and ultralow output noise. This LDO uses an advanced BiCMOS process to achieve very good electrical performance. It is an ideal choice for noise sensitive Analog RF FrontEnds used in Telecom Equipment. The NCP59800 is available in the 3 mm x 3 mm DFN8 package. 1 Features DFN8 3 x 3 mm Operating Input Voltage Range: 2.2 V to 6.0 V CASE 506DB Output Voltage Range: 0.8 V to 5 V (adjustable) Quiescent Current typ. 60 A MARKING DIAGRAM Low Dropout: 200 mV typ. at 1 A, V = 2.5 V OUT 1 59800 2.5% V Accuracy across Load/Line/Temperature OUT ADJB Stable with Small 4.7 F Ceramic Capacitors ALYW VeryLow Noise: Typically 15 V from 100 Hz to 100 kHz RMS OverCurrent and Thermal Shutdown Protection A = Assembly Location L = Wafer Lot Available in 3 x 3 mm DFN8 Package Y = Year These Devices are PbFree, Halogen Free/BFR Free and are RoHS W = Work Week Compliant = PbFree Package (Note: Microdot may be in either location) Typical Applications Telecom Infrastructure Audio PIN CONNECTIONS HighSpeed I/F (PLL/VCO) OUT IN NCP59800 IN OUT V V OUT IN IN OUT FB/SNS NR C IN C OUT GND EN EN FB R 1 4.7 F 1 F (Top View) NR GND 3 mm x 3 mm DFN8 0.65 P R 2 10 nF Optional ORDERING INFORMATION Figure 1.

PIN FUNCTION DESCRIPTION Pin No. DFN8 Pin Name Description 7,8 IN Unregulated input supply. 4, EPAD GND Ground. 5 EN Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into shutdown mode. 6 NR Connect an external capacitor between this pin and ground to reduce the output noise to very low levels. The capacitor slows down the V ramp as well (softstart). OUT Max recommended C value is 0.47 F NR 3 FB This pin is the input to the control loop error amplifier and is used to set the output voltage of the device. 1,2 OUT Regulator output. A 4.7 F to 100 F capacitor is required for stability. Table 2.
