NCP508: Linear Voltage Regulator, LDO, Low Noise, Fast Turn On, 50 mA

The NCP508 is a 50 mA low noise, low dropout (LDO) linear voltage regulator, designed to exhibit fast turn-on time, low noise and high ripple rejection. The device is robust, incorporating current limiting and temperature protection circuitry. The NCP508 has been designed for use with low cost ceramic capacitors and is housed in an SC-88A or a tiny 1.5x1.5 mm WDFN package. Standard voltage versions are 1.5, 1.8, 2.5, 2.8, 3.0, and 3.3. Other voltages may be available, along with Automotive qualified versions of the device: contact your local sales representative.

特性
  • Very Low Noise at 39 uVrms without a Bypass Capacitor
  • Fast enable response (20 usec)
  • High Ripple Rejection of 70 dB at 1 kHz
  • Can use decoupling capacitors with ESR ranging from milliohms to 3 ohms.
优势
  • Suitable for audio or measurement applications
  • Responds quickly to a turn-on signal
  • Provides a clean voltage rail from a battery or noisey supply
  • Suitable for cheap ceramic capacitors
应用
  • RF Subsystems in Handsets
  • Noise sensitive circuits; VCOs, PLL
终端产品
  • Bluetooth headsets
  • Meters, Instrumentation
