EM1101
300mA High PSRR Low Noise, Adjustable LDO Regulator
General Description
The EM1101 performs ultra low drop voltage,
high power supply rejection ratio (PSRR), fast
response, low noise linear regulator, and designed
to continuously deliver up to 300mA output current.
The EM1101 has wide adjustable output voltage
range and high feedback voltage accuracy to 1.5%.
No by-pass capacitor is needed for this device
and only 1uF 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 EM1101 is
available in SOT-23-5 package.
