SOT-25
The
UR6223
series is a high speed LDO regulator that features
high accurate, low noise, high ripple rejection, low dropout and low
power consumption. The series 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 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.
