1A BiCMOS Very Low Dropout Regulators

M I C R O S E M I

C O M P A N Y

PRELIMINARY DATASHEET

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.

V_IN

Mcrosemi

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.

V_OUT

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.

GND

ADJ

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_Ais the resistor connected between V_OUTand

ADJ, and R_Bis 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.
