TECHNICAL DATA
LOW Noise150mA CMOS High Performance LDO Regulator
The KIC3211series Low Dropout Linear Regulator is ideally suited
for portable applications. It offers 1% initial accuracy,
extremely-low dropout voltage(220mV at 150mA, 3.0V Output Type)
and low ground current (typically 75uA). Designed specifically for handheld
and battery-powered devices, the KIC3211series provides a
TTL-logic-compatible ON/OFF control pin. When disabled,
power consumption drops nearly to zero.
The KIC3211series also works with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power applications,
critical in handheld wireless devices.
The Line transient response and load transient response of the
KIC3211T/SN Series are very excellent, thus ICs are very suitable for
the power supply for hand-held communication equipment.
