L1131B
DESCRIPTION The UTC L1131B is a S positive linear regulator. One of it’s feature is the very low quiescent current typical as low as 1.5μA and its dropout voltage is extremely low with 200m A output current, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an error amplifier, resistor-net for voltage setting, a short current limit circuit, a chip enable circuit, and so on. These ICs perform with low dropout voltage and the chip-enable function. The supply current at no load of this IC is only 1.5μA, and the line transient response and the load transient response of the UTC L1131B Series are excellent, thus these ICs are very suitable for the power supply for hand-held munication equipment. 2 1 SOT-23 (EIAJ SC-59) 4 5 SOT-25 (JEDEC MO-178) CMOS IC 4 5 SOT-23-5 (JEDEC TO-236) 1 SOT-89 - FEATURES - Low supply current Typ. 1.5μA - Standby mode Typ. 0.1μA - Output Voltage Range 1.2V ~ 5.0V - Built-in fold back protection circuit - Ceramic...
