General Description

The EM1109BV 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 EM1109BV 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 EM1109BV is available

in DFN3X3-08L package.
