NCP508
Very Low Noise, Fast Turn
On, 50 mA Low Dropout
Voltage Regulator
The NCP508 is a 50 mA low noise voltage regulator, designed to
12
exhibit fast turn on time and high ripple rejection. Each device
contains a voltage reference unit, an error amplifier, a PMOS power
transistor, resistors for setting output voltage, current limit, and
temperature limit protection circuits.
The NCP508 has been designed for use with ceramic capacitors.
The device is housed in SC ? 88A and WDFN6 1.5x1.5 packages.
Standard voltage versions are 1.5, 1.8, 2.5, 2.8, 3.0, and 3.3. Other
voltages are available in 100 mV steps.
