SE5120

The SE5120 series of fixed output low dropout linear regulators are designed for portable battery powered applications, which require low power consumption and low dropout voltage. Each device contains a bandgap voltage reference, an error amplifier, a PMOS power transistor, and resistors for setting output voltage, and current limit and temperature limit protection circuits.

The SE5120 has been designed to be used with low cost capacitors and requires a minimum output capacitor of 1.0F. Standard voltage versions are 3.3, 3.0V, and adjustable output from 0.8V to 4.5V.
