2 AMP ADJUSTABLE LOW VOLTAGE INPUT  
INTEGRATED SWITCHING REGULATOR  
• Low Voltage Input (7V)  
• 89% Efficiency  
• Adjustable Output Voltage  
• Internal Short Circuit Protection  
• Over-Temperature Protection  
• On/Off Control (Ground Off)  
Regulators (ISRs). These ISRs are de-  
signed with premium low threshold FETs  
for those applications requiring very low  
input/output voltage differentials such as  
battery powered equipment. This high-  
performance ISR family offers a unique  
combination of features combining 89%  
typical efficiency with open-collector on/  
off control and adjustable output voltage.  
Quiescent current in the shutdown mode  
is less than 100µA.  
The PT6220 series is a low volt-  
age input (typically 7V) version of  
Power Trends’ high-performance

ISR will operate to no load with reduced specifications.  
** Input voltage cannot exceed 30V when the inhibit function is used. *** See Thermal Derating chart  
Note: The PT6220 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications.
