EM1109A

1A Low Dropout and Adjustable Mode Regulator

General Description

Applications

The EM1109AV-AD performs ultra- low drop

voltage, high power supply rejection ratio (PSRR),

fast response, low noise linear regulator, and

designed to continuously deliver up to 1A output

current. The EM1109AV-AD has wide adjustable

output voltage range and high output accuracy to

1.0%.

No by-pass capacitor is needed for this device and

only 4.7uF ceramic capacitor is required for stability

in any loading conditions. It reduces the amount of

board space necessary for power applications.

The other features include soft start, current limit

protection, Power-On-Reset function, and over

temperature protection. The EM1109AV-AD is

available in DFN3.0X3.0-08 package.
