XC6213Series
ETR0308_004
High Speed LDO Regulators, Low ESR Cap. Compatible, Ultra Small Package
■GENERAL DESCRIPTION
The XC6213 series is a highly precise positive voltage LDO regulator with low noise manufactured using CMOS process. The
series achieves high ripple rejection and low dropout and consists of a voltage reference, an error amplifier, a current limiter
and a phase compensation circuit plus a driver transistor. Output voltage is selectable in 50mV increments within a range of
1.2V to 5.0V. The series is also compatible with low ESR ceramic capacitors, which give output stability. The current limiter's
foldback circuit also operates as a short circuit protection for the output pin. The CE function enables the output to be turned
off, resulting in greatly reduced power consumption. Ultra small package SSOT-24, SOT-25, and USP-4 are available.
