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 0.05V 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, USPN-4 and USP-4 are available.
The XC6213 Series is a highly precise positive‑voltage LDO regulator with low noise, offering selectable output voltages in 0.05 V steps from 1.2 V to 5.0 V. It includes a voltage reference, error amplifier, current limiter with fold‑back protection, and a phase‑compensation circuit, and it can be powered from 2.0 V to 6.0 V.
