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.
V IN , EN ..................................................... -20V to +20V
Power Dissipation ................................ Internally Limited
Lead Temperature (Soldering, 5 sec) ..................... 260°C
ESD Rating (HBM - Human Body Model) .................... 2kV
OPERATING RATINGS
Input Voltage Range V IN ................................ 2.5V to 16V
Enable Pin EN ............................................... 0.0V to V IN
Junction Temperature Range ................. -40°C to +125°C
Thermal Resistance 1 .....................................................
θ JA (SOT23-5)...............................................191°C/W
θ JA (NSOIC-8)............................................ 128.4°C/W
θ JA (DFN-8) ................................................... 59°C/W
Note 1: The maximum allowable power dissipation is a
function of maximum operating junction temperature,
T J(max) the junction to ambient thermal resistance, and the
ambient θ JA , and the ambient temperature T A . The
maximum allowable power dissipation at any ambient
temperature is given: P D(max) = (T J(max) -T A )/θ JA , exceeding
the maximum allowable power limit will result in excessive
die temperature; thus, the regulator will go into thermal
shutdown
ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Junction Temperature of T J = 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 (V IN = V OUT + 1.2V for 1.2V option), I L = 100μA, C L =
1μF, V EN ≥ 2.5V, T A = T J = 25°C.
