XC6229Series

ETR0362-004

300mA Ultra Small High Speed LDO Regulator, Built-in Inrush Current Protection

■GENERAL DESCRIPTION

The XC6229 series is a high speed LDO regulator that features high accurate, low noise, high ripple rejection, low dropout and

low power consumption. Housed in the ultra-small LGA-4B01 (0.75 x 0.75, h=0.3mm MAX.) package, the XC6229 is ideal for

space-saving design. The XC6229 consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a phase

compensation circuit, a thermal shutdown circuit and an inrush current protection circuit.

The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the series

enables the electric charge at the output capacitor CL to be discharged via the internal switch, and as a result the VOUT pin

quickly returns to the VSS level. The output stabilization capacitor CL is also compatible with low ESR ceramic capacitors.

The output voltage is selectable in 0.05V increments within the range of 1.2V to 4.0V which fixed by laser trimming

technologies. The over current protection circuit and the thermal shutdown circuit are built-in. These two protection circuits will

operate when the output current reaches current limit level or the junction temperature reaches temperature limit level.
