Low, 90µA No-Load Supply Current  
The G924 is a low supply current, low dropout linear  
regulator that comes in a space saving SOT-23-5  
package. The supply current at no-load is 90µA. In the  
shutdown mode, the maximum supply current is less  
than 1µA. Operating voltage range of the G924 is from  
2.5V to 5.5V. The over-current protection limit is set at  
550mA typical and 400mA minimum. An over-tem-  
perature protection circuit is built-in in the G924 to  
prevent thermal overload. These power saving fea-  
tures make the G924 ideal for use in the battery- pow-  
ered applications such as notebook computers, cellu-  
lar phones, and PDAs.  
Guaranteed 300mA Output Current
