Description
Features
¾
Typical Low Dropout Voltage of 203mV at
The SE5166 series of fixed output low dropout
linear regulators are designed for portable battery
powered applications, which require low dropout
voltage and low ground current. 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.
