1 / 7 page UNISONIC TECHNOLOGIES CO., LTD LR9200 CMOS IC www.unisonic.com.tw 1 of 7 Copyright © 2013 Unisonic Technologies Co., Ltd QW-R502-955,A LOW NOISE 200mA LDO REGULATOR DESCRIPTION The UTC LR9200 is a typical LDO with the features of high output voltage accuracy, low supply current, low ON-resistance, and high ripple rejection. During operation of the UTC LR9200, 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 LR9200 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 LR9200. The UTC LR9200 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: 20µA (Typ.) *Standby Mode: 0.1µA (Typ.) *Very Low Dropout Voltage: 0.13V (Typ.) @IOUT =150mA, VOUT =2.85V *Ripple Rejection: 75dB (Typ.) @f=1kHz,VOUT=2.85V *Temperature-Drift Coefficient of Output Voltage: ±30ppm/°C (Typ.) *Well Line Regulation: 0.02%/ V (Typ.) *Output Voltage Accuracy: ±0.8% (Typ.) *Internal Fold Back Protection Circuit: 40mA (Typ.) @ short mode *CIN=COUT=1µF or more (Ceramic capacitors) are recommended to be used with this IC ORDERING INFORMATION Ordering Number Package Pin Assignment Packing Lead Free Halogen Free 1 2 3 4 5 LR9200L-xx-AF5-R LR9200G-xx-AF5-R SOT-25 VIN G CE NC O Tape Reel LR9200L-xx-AB3-C-R LR9200G-xx-AB3-C-R SOT-89 G I O - - Tape Reel Note: xx: Output Voltage, refer to Marking Information. |
