DESCRIPTION
The IXD1209/12 are a highly precise, low noise,
positive voltage LDO regulators manufactured using
CMOS processes. The IXD1209/12 have a high
ripple rejection factor and low dropout. They consist
of a voltage reference, an error amplifier, a current
limiter, a phase compensation circuit, and a driver
transistor.
Output voltage is selectable in 0.05V increments
within a range of 0.9 V ~ 6.0 V.
The IXD1209/12 are compatible with low ESR
ceramic capacitors, and due excellent transient
response, they maintain stability even during
significant load fluctuations. The current limiter's
foldback circuit operates also as a short circuit
protection.
The chip enable (CE) function allows disable IC,
greatly reducing power consumption.
Regulator
is available in SOT-25, SOT-89-5, and
USP-6B packages.
