DESCRIPTION
The IRU1502-33 is a PMOS low dropout, linear regulator
and it is capable of supplying 1A of continuous current
over line and temperature range. The IRU1502-33 is
stable with low value ceramic capacitors, ensures low
noise operation, improves load transient response and
enables a smaller circuit size.
IRU1502-33 features ultra low noise, fast start-up and
an excellent time and load response. This device also
includes built-in output protection with both current limit
and thermal shutdown.
