LR9270 Datasheet | Unisonic Technologies

DESCRIPTION The UTC LR9270 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 LR9270, 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 LR9270 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 LR9270. The UTC LR9270 can be used as an ideal of the power supply for hand-held munication equipment, such as: power source for portable munication equipment, power source for electrical appliances, for example, cameras, VCRs and camcorders and power source for battery-powered equipment. - FEATURES - Low standby current - Ultra-Low supply current - Output voltage (stepwise setting with a step of 0.1V in the range of 1.2V~4.0V) - Output current (MIN=800m A@VIN=VOUT+1.0V) - Low dropout voltage - Line regulation - High output voltage accuracy - Low temperature-drift coefficient of output voltage - Built-in thermal shunt circuit - Built-in current limit circuit - ORDERING INFORMATION Ordering Number Lead Free Halogen Free LR9270x L-xx-AB5-R LR9270x G-xx-AB5-R LR9270x L-xx-AE5-R LR9270x G-xx-AE5-R LR9270x L-xx-AF5-R LR9270x G-xx-AF5-R Package SOT-89-5 SOT-23-5 SOT-25 4 5 SOT-89-5 1 2 3 SOT-25 4 5 1 2 3 SOT-23-5 (JEDEC TO-236) Packing Tape Reel Tape Reel Tape Reel LR9270x G-xx-AB5-R (1)Packing Type (2)Package Type (3)Output Voltage Code (4)Green Package (5)Enable Threshold Level (1) R: Tape Reel (2) AB5: SOT-89-5, AE5: SOT-23-5, AF5: SOT-25 (3) xx: refer to Marking Information (4) G: Halogen Free and Lead Free, L: Lead Free (5) H: High, L: Low .unisonic..tw Copyright © 2019 Unisonic Technologies Co.,...
