■GENERAL DESCRIPTION
The XC6215 series are highly precise, low noise, positive
voltage LDO regulators manufactured using CMOS processes.
The series achieves very low supply current, 0.8µA (TYP.) and
consists of a reference voltage source, an error amplifier, a
current foldback circuit, and a phase compensation circuit plus
a driver transistor.
Ultra small packages USP-3, USP-4, and SSOT-24, and small
package SOT-25 packages make high density mounting
possible. Therefore, the series is ideal for applications where
high density mounting is required such as in mobile phones.
Output voltage is selectable in 100mV increments within a
range of 0.9V ~ 5.0V by laser trimming
The series is also compatible with low ESR ceramic capacitors,
which give added output stability.
The current limiter's foldback circuit also operates as a short
protect for the output current limiter and the output pin.
Furthermore, the CE function allows the output of the regulator
to be turned off, resulting in greatly reduced power
