SP2525
Low ESR Cap. & Low Power High-speed CMOS LDO
DESCRIPTION
The SP2525 series are highly precise, low noise,
positive voltage LDO regulators manufactured using
CMOS processes. The series achieves high ripple
rejection and low dropout and consists of a standard
voltage source, an error correction, 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 feedback circuit also
operates as a short protect for the output current limiter
and the output pin.
The SP2525 family is compatible with low ESR
capacitors. The current limiter's feedback circuit also
operates as a short protect for the output current limiter.
The SOT-23-3L / SOT-353 packages are available for
portable electronic equipment.
