The SE5232 series of fixed output low dropout
linear regulators are designed to meet the new
requirements of high PSRR， fast dynamic
response, low noise, low dropout voltage and
low power consumption in today's portable
battery powered applications such as cellular
phones,
surveillance
system,
Bluetooth,
wireless and other portable electronic devices.
The short-circuit protection has a fold-back
current limiter which will reduce the excessive
heat during short circuiting. SE5232 also have
standard Over-Temperature Protection
The SE5232 are available in standard
SOT23-5L, SOT89 and DFN1x 1-4L packages.
Standard products are Halogen-free.
