1 UNISONIC TECHNOLOGIES CO., LTD LOW NOISE ma LDO REGULATOR DESCRIPTION The UTC is a typical LDO (linear regulator) with the features of High output voltage accuracy, low supply current, low ON-resistance, and high ripple rejection. During operation of the UTC, the dropout voltage is very low and the response of line transient and load transient are very well. Internally, there re many functions of UTC which can be seen in the block figure. There are a voltage reference unit, an error amplifier, resistor-net for voltage setting, a current limit circuit, and a chip enable circuit in each UTC. The UTC can be used as an ideal of the power supply for hand-held communication equipment, such as: power source for portable communication equipment, power source for electrical appliances, for example, cameras, VCRs and camcorders and power source for battery-powered equipment. FEATURES * Ultra Supply Current: 8µA (Typ.) * Standby Mode:.µA (Typ.) * Very Low Dropout Voltage:.V =5mA, V =.85V * : 75dB =.85V * Temperature-Drift of : ±ppm/ C (Typ.) * Well :.%/ V (Typ.) * Accuracy: ±.8% (Typ.) * Internal Fold Back Protection Circuit: ma short mode * C =C =µf or more (Ceramic capacitors) are Recommended to be used with this IC ORDERG FORMATION Ordering Number Package Packing G-xx-AF5-R SOT-5 Tape Reel Note: xx:, refer to Marking Information. of Copyright Unisonic Technologies Co., Ltd
