1 / 20 page © Semiconductor Components Industries, LLC, 2006 February, 2006 − Rev. 19 1 Publication Order Number: NCP500/D NCP500 150 mA CMOS Low Noise Low−Dropout Voltage Regulator The NCP500 series of fixed output low dropout linear regulators are designed for portable battery powered applications which require low noise operation, fast enable response time, and low dropout. The device achieves its low noise performance without the need of an external noise bypass capacitor. Each device contains a voltage reference unit, an error amplifier, a PMOS power transistor, and resistors for setting output voltage, and current limit and temperature limit protection circuits. The NCP500 has been designed to be used with low cost ceramic capacitors and requires a minimum output capacitor of 1.0 mF. Features • Ultra−Low Dropout Voltage of 170 mV at 150 mA • Fast Enable Turn−On Time of 20 msec • Wide Operating Voltage Range of 1.8 V to 6.0 V • Excellent Line and Load Regulation • High Accuracy Output Voltage of 2.5% • Enable Can Be Driven Directly by 1.0 V Logic • Typical RMS Noise Voltage 50 mV with No Bypass Capacitor (BW = 10 Hz to 100 kHz) • Very Small DFN 2x2.2 Package • Pb−Free Packages are Available Typical Applications • Noise Sensitive Circuits − VCO’s, RF Stages, etc. • SMPS Post−Regulation • Hand−Held Instrumentation • Camcorders and Cameras Driver w/ Current Limit Vin Vout Thermal Shutdown Enable GND OFF ON 1 (3) 3 (1) 5 (4) 2 (2, 5) Figure 1.
