• Low dropout voltage VDIF ≤ 0.6 V (IO = 1 A)  
*1: VIN (max) and IO (max) are restricted by the relation PD = (VIN - VO) × IO. Please calculate these values referring to the  
Copper laminate area vs. Power dissipation data as shown hereinafter.  
*2: When mounted on a glass epoxy board of 1600 mm2 (copper laminate area 2%).  
• 3 types of output voltages (2.5 V, 3.3 V, and  
variable type) available  
• Output ON/OFF control terminal voltage  
compatible with LS-TTL  
• Built-in drooping-type-overcurrent and thermal  
protection circuits  
■Applications  
• Local power supplies  
• Battery-driven electronic equipment  
■Electrical Characteristics

*1: Refer to the Dropout Voltage parameter.  
*2: The Is1 is specified at the 5% drop point of output voltage VO on the condition that VIN = VO + 1 V, and IO = 10 mA.  
*3: Output is OFF when the output control terminal VC is open. Each input level is equivalent to LS-TTL level. Therefore, the device can be driven directly by LS-TTLs.
