ABSOLUTE MAXIMUM RATINGS (1)  
Supply Voltage VIN ......................................... 6V  
Thermal Resistance (4)  
TSOT23-8..............................100..... 55... °C/W  
θJA  
θJC  
V
SW........................ (-3V for < 5ns) to (VIN+0.3V)  
Notes:  
1) Exceeding these ratings may damage the device.  
2) The maximum allowable power dissipation is a function of the  
maximum junction temperature TJ (MAX), the junction-to-  
ambient thermal resistance θJA, and the ambient temperature  
TA. The maximum allowable continuous power dissipation at  
any ambient temperature is calculated by PD (MAX) = (TJ  
(MAX)-TA)/θJA. Exceeding the maximum allowable power  
dissipation will cause excessive die temperature, and the  
regulator will go into thermal shutdown. Internal thermal  
shutdown circuitry protects the device from permanent  
damage.  
All Other Pins.................................-0.3V to +6 V  
Junction Temperature...............................150°C  
Lead Temperature ....................................260°C  
(2)  
Continuous Power Dissipation (TA = 25°C)  
……….….. ............................................... 1.25W  
Storage Temperature............... -65°C to +150°C  
Recommended Operating Conditions (3)  
Supply Voltage VIN ..........................2.5V to 5.5V  
Output Voltage VOUT.................0.6V to VIN -0.5V  
Operating Junction Temp. (TJ). -40°C to +125°C  
3) The device is not guaranteed to function outside of its  
operating conditions.  
4) Measured on JESD51-7, 4-layer PCB.
