xc6220b331mr-g:LDO Voltage Regulators 1A High Speed Green Operation Vltg Reg

The XC6220 series is a CMOS voltage regulator with Green Operation that is highly accurate, low noise, fast, has a low dropout, and has a large current. A voltage reference, an error amplifier, a current limiter, an inrush current prevention circuit, a phase compensation circuit, and a driver transistor are all part of the series.

The ultra-low dropout voltage performance with output currents up to 1A with a 0.2 on-resistance driver transistor integrated greatly extends battery life, as does the Green Operation function, which can switch between high speed and power save modes automatically. For the output stabilization capacitor, a low ESR ceramic capacitor can be used (CL).

Using laser trimming technologies, the output voltage can be adjusted in 0.05V increments within a range of 0.8V5.0V. There is an overcurrent protection circuit as well as a thermal shutdown circuit built-in. When the output current reaches its limit current, the over-current protection circuit kicks in. When the junction temperature reaches its limit temperature, the thermal shutdown circuit will activate. The inrush prevention circuit controls the inrush current that charges to CL when the IC starts up. Voltage fluctuations in the power supply caused by inrush current during system startup can thus be reduced.

The CE function allows the output to be disabled and the IC to enter a standby mode, resulting in significantly reduced power consumption.

* The No.5 and 6 VIN pins should be connected. The No.1 and 2 pins VOUT pins should be connected. The dissipation pad for the USP-6C package should be solder-plated in recommended mount pattern and metal masking to enhance mounting strength and heat release. If the pad needs to be connected to other pins, it should be connected to the VSS (No. 4)
