XC6229
Series
■GENERAL
DESCRIPTION
ETR0362-004
300mA Ultra Small High Speed LDO Regulator, Built-in Inrush Current Protection
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 C
L
to be discharged via the internal switch, and as a result the V
OUT
pin
quickly returns to the V
SS
level. The output stabilization capacitor C
L
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.
