SP2524

SP2524 Low ESR Cap. & Low Power High-speed CMOS LDO With CE Pin DESCRIPTION The SP2524 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 CE function enables the output to be turned off, resulting in greatly reduced power consumption. The SP2524 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-23-5L / SOT-353 packages are available for portable electronic equipment.
