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 VIN1................................................... 20V
Storage Temperature .............................. -65°C to 150°C
Lead Temperature (Soldering, 5 sec) ..................... 260°C
ESD Rating (HBM - Human Body Model) ..........................
All pins except EN................................................. 2kV
En pin ................................................................. 1kV
OPERATING RATINGS
Input Voltage Range VIN........................................... 16V
Junction Temperature Range ....................-40°C to 125°C
Thermal Resistance ......................................................
TO-220 Junction to Case @ TA ............................ 3°C/W
TO-220 Junction to Ambient ............................. 60°C/W
TO-263 Junction to Case @ TA ............................ 3°C/W
TO-263 Junction to Ambient ............................. 60°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 TJ = TA = 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 TJ = 25°C, and are provided for
reference purposes only. Unless otherwise indicated, VIN = VOUT + 1V and IOUT=10mA, CIN = 6.8µF, COUT = 10µF, TA= 25°C.

Note 2: Full load current (IFL) is defined as 3.0A.
Note 3: Dropout voltage is defined (VIN-VOUT) when the output voltage drops to 99% of its nominal value.
Note 4: VIN=VOUT(nom)+1V. Use pulse-testing procedures to minimize temperature rise.
