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 1.0F output capacitor for stability with a load up to 300mA and consumes less than 1A in shutdown mode.

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.
