General Description
The PAM3106 series are precise, low noise,
positive voltage LDO regulators manufactured
using CMOS processes. The series achieves high
ripple rejection and low dropout and consists of a
voltage reference, an error amplifier, a current
limiter and a phase compensation circuit plus a
driver transistor.
The series is also compatible with low ESR
ceramic capacitors which give added output
stability. This stability can be maintained even
during load fluctuations due to the excellent
transient response of the series.
The current limiter's foldback circuit also
operates as a short protect for the output current
limiter and the output pin.
The EN function enables the output to be turned
off, resulting in greatly reduced power
consumption.
