The XC6420 is the latest generation of dual channel CMOS LDO Regulators from Torex Semiconductor.

Comprising two independent LDO circuits, each able to deliver 150mA, the XC6420 is available in a USPN-6 package which measures 1.3 x 1.3mm with a maximum height of 0.4mm.

The chip delivers high PSRR (75dB at 1kHz), low drop-out voltage (190mV@150mA) and low noise operation making it suitable for both RF and Digital applications. 

Power consumption is only 55μA per channel. Each output voltage can be set-up independently within a range of 1.2V to 3.6V, in 0.05V steps with a ±2% tolerance.

Both channels can be controlled independently using separate EN pins and in standby mode the current consumption reduces to 0.1μA.

The XC6420 is fully compatible with low ESR ceramic capacitors and includes a CL discharge function with a dedicated internal switch to ensure the VOUT pin quickly returns to the VSS level when the LDO is shut-down via the EN pin.
