Product Overview
NCP508: Linear Voltage Regulator, LDO, Low Noise, Fast Turn On, 50 mA
For complete documentation, see the data sheet
Product Description
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.
