3A Low Dropout Voltage Regulator
ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect
reliability.
Input Voltage V_IN1 ................................................... 20V
Storage Temperature .............................. -65°C to 150°C
Lead Temperature (Soldering, 5 sec) ..................... 260°C
ESD Rating (HBM - Human Body Model) ..........................

OPERATING RATINGS
Input Voltage Range V_IN........................................... 16V
Junction Temperature Range ....................-40°C to 125°C
Thermal Resistance ......................................................
TO-220-5 Junction to Ambient ....................... 29.3°C/W
TO-263-3 Junction to Ambient ....................... 31.4°C/W
TO-263-5 Junction to Ambient ....................... 31.2°C/W
TO-220-5, TO-263-3, TO-263-5 Junction to Case .. 3°C/W
Note 1: Maximum positive supply voltage of 20V must be
of limited duration (<100ms) and duty cycle of less than
1%. The maximum continuous supply voltage is 16V.
ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Junction Temperature of T_J = T_A = 25°C only; limits applying over the
full Operating Junction Temperature range are denoted by a “•”. Minimum and Maximum limits are guaranteed through test,
design, or statistical correlation. Typical values represent the most likely parametric norm at T_J = 25°C, and are provided for
reference purposes only. Unless otherwise indicated, V_IN = V_OUT + 1V and I_OUT=10mA, C_IN = 6.8µF, C_OUT = 10µF, T_A= 25°C.
