Positive supply input for the regulator. Bypass to GND with at least 2.2μF of low ESR, ESL capacitance if
supply source is further than 1 inch from the device.
Output for the regulator. It is recommended to bypass to GND with at least 10μF although this is not required
for regulation, rather it is needed for transient response. Size your output capacitor to meet the transient
loading requirement. If you have a very dynamic load, a larger capacitor will improve the response to these
load steps.
Reference ground. The input and output bypass capacitors should be connected to this pin. In addition the tab
on the SOT-223 package and pins 2,3,6, and 7 on the SOIC package are also used for heat sinking the device.
Feedback pin for the regulator. For the LX8610-00, the output voltage can be set by two external resistors with
the following relationship: V
OUT
= 1.25V * (1 + R
A
/ R
B
) where R
A
is the resistor connected between V
OUT
and
ADJ, and R
B
is the resistor connected between ADJ and GND.
Enable input. This pin has a threshold of about V
IN
/ 2, it should be actively pulled high to enable the regulator.
This can be accomplished with a resistive pull-up. When low, it turns off the regulator and puts the device in a
low current shutdown state.
