Description

The YB1211 is a low-noise, low dropout (LDO) linear

regulator with enable function and external

adjustable output voltage. It operates at an input

supply of 2.0~6.0V and is able to output voltages

ranging from 1.23V (The YB1211 internal reference

voltage) to 5V by a feedback from a pair of resistor

divider.

The YB1211 regulators are optimized to work with

low-ESR and low cost ceramic capacitors, reducing

the amount of board space critical in portable

devices. The YB1211 requires only 1.0μF output

capacitor for stability with a load up to 300mA and

consumes less than 1μA in shutdown mode.

Applications

Built-in thermal shutdown and short-circuit protect

offer secure protection against fault operation. The

YB1211 regulators are available in a small SOT-25

package.
