Description
The SE5508 series of fixed output low dropout linear regulators are designed for portable battery powered applications, which require low noise environment, fast enable response time, and low dropout voltage. An optional bypass capacitor can be added for better low-noise performance. Each device contains a voltage reference unit, an error amplifier, a PMOS power transistor, and resistors for setting output voltage, and current limit and temperature limit protection circuits.
