150mA CMOS LDO regulator in a 5-lead SOT-23 package,
featuring 120mV dropout at 100mA levels and nearly negli-
gible dropout below 5mA.
The part offers 2% precision as standard, yet draws only
5A of current in operation and drops to 0.5A in shutdown.
The outputs offer short-circuit protection, and the shutdown
pin has an internal pull-down which will disable the output if
the pin is left floating.

Note:
1. V
OUT
means the output voltage when "V
OUT
+ 1.0V" is provided at the V
IN
pin while maintaining a certain I
OUT
value.
2. V
IN
1 is defined as the input value that is gradually decreased until the output value reaches V
OUT
x 98%.
3. V
dif
is defined as "V
IN
1-V
OUT.
"
4. I
OUT
: this is limited by continuous total power dissipation in the package.
5. When V
CE
is LOW or OPEN, the output is disabled.
Note: CE pin is a CMOS input. Because of this, when the input voltage reaches V
IN
/2, a rush current will start to flow.
