LR9272 Datasheet | Unisonic Technologies

DESCRIPTION The UTC LR9272 is a typical LDO (linear regulator) with the features of high output voltage accuracy, low supply current, low ON-resistance, super low dropout, 1A output current capability, and high ripple rejection. During operation of the UTC LR9272, the dropout voltage is very low, Even the output voltage is set at 1.5V, on resistance of internal FET is typically 0.32Ω. Therefore, applications that require a large current at small dropout are suitable for the UTC LR9272 series. Low input voltage is acceptable and low output voltage can be set. The minimum input voltage is 1.4V, and the lowest set output voltage is 0.8V, and the response of line transient and load transient are very well. Internally, there’re many functions of UTC LR9272 which can be seen in the block figure. There are a voltage reference unit, an error amplifier, resistor-net for voltage...
