low dropout regulator rated for 300mA output current. The
low power consumption and high accuracy is achieved
through CMOS technology and internal trimmed reference
voltage.
reference, error correction circuit, and a current limit output
driver. The fast transient response is an outstanding feature
for applications with various loads.
