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  
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 SC88A 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.
