Description
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 1.0碌F.
0.8V to 4.5V.
Standard voltage
versions are 3.3, 3.0V, and adjustable output from
