ABSOLUTE MAXIMUM RATINGS
Input Voltage (VIN) ....................................................................................................... 10V
Load Current (Internally Limited)................................................................................... 2A
Power Dissipation ................................................................................... Internally Limited
Short-Circuit Protection ........................................................................................Indefinite
Operating Junction Temperature................................................................................ 150°C
Storage Temperature Range........................................................................ -65°C to 150°C
RoHS / Pb-free Peak Package Solder Reflow Temperature
(40 second maximum exposure) ....................................................................260°C (+0,-5)
Note: Exceeding these ratings could cause damage to the device. All voltages are with respect to
Ground. Currents are positive into, negative out of specified terminal.
THERMAL DATA

THERMAL RESISTANCE-JUNCTION TO TAB, θJT
THERMAL RESISTANCE-JUNCTION TO AMBIENT, θJA
(Typical, depending on mounting/pcb layout)
8°C/W
29-35°C/W
Junction Temperature Calculation: TJ = TA + (PD x θJA).
The θJA numbers are guidelines for the thermal performance of the device/pc-board
system. All of the above assume no ambient airflow. θJA can vary significantly depending
on mounting technique. (See Application Notes Section: Thermal considerations)

FUNCTIONAL PIN DESCRIPTION
DESCRIPTION
Positive unregulated supply input for the regulator. Bypass to GND with at least 2.2µF of low ESR and ESL
capacitance.
Common terminal for ground reference. The input and output bypass capacitors should be connected to this
pin.
Regulator output. It is recommended to bypass to GND with at least 2.2µF. Size your output capacitor to meet
the transient loading requirement. If you have a very dynamic load, a lower ESR capacitor will improve the
response to these load steps.
