The XC6204 series are high precision, 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 1.8V ~ 6.0V. 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 foldback 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 XC6204 series from Torex are precision, low‑noise LDO regulators with selectable output voltages from 1.8 V to 6.0 V in 50 mV steps. They feature high ripple rejection, low dropout (as low as 60 mV at 30 mA), and are compatible with low‑ESR ceramic capacitors for stable operation under load transients.
The device includes an integrated current limiter with fold‑back protection, a CE ON/OFF pin, and a CE pin logic that can be configured as active‑high or active‑low with optional pull‑up/pull‑down resistors. Typical applications include mobile phones, cameras, portable AV equipment, and battery‑powered devices.
