description  
The SN105125 is a low dropout voltage regulator with an output tolerance of ±2% over the operating range. The  
device is optimized for low noise applications and has a low quiescent current (enable <0.8 V). The device has  
a low dropout voltage at full load (150 mA). The power okay function monitors the output voltage and indicates  
when an error occurs in the system (active low). In the event of an output fault such as overcurrent, thermal  
shutdown, or dropout, the power okay output is pulled low (open drain).  
The SN105125 has a fast transient response recovery capability in the event of load transition from heavy load  
to light load. The device also minimizes overshoot during this condition. During power down, the output  
capacitor and load are de-energized through the internal active shutdown clamp, which is turned on when the  
device is disabled.  
The SN105125 requires a small output capacitor for stability with low ESR. An input capacitor is not required  
unless the bulk ac capacitor is placed away from the device or the power supply is a battery. In this situation,  
a 1-µF capacitor is recommended for the application. Low ESR ceramic capacitors may be used with the device  
to reduce board space in power applications, a key concern in hand-held wireless devices.
