Low ESR Low Power High-Speed CMOS LDO

DESCRIPTION

ST6205 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. Output voltage is selectable
in 50mV increments within a range of 1.5V~5.0V. 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. ST6205 family is
compatible with low ESR capacitors. The current limiter’s feedback circuit also operates
as a short protect for the output current limiter.
