Technologies The 79D12AL-TN3-R is an Unisonic Technologies Low Dropout (LDO) Linear Voltage Regulator with a voltage ranging from 3.3V to 12V. It has high output current up to 1.2A and low quiescent current. The device is based on CMOS technology, is RoHS compliant, and is packaged in a TO-252-2 (DPAK) package. It is suitable for applications requiring an efficient and low cost power supply. The 79D12AL-TN3-R features a very low dropout voltage (typically 230mV @ 1A), making it ideal for powering sensitive electronics such as cellular phones, PDAs, and notebooks. It also features fast start-up, excellent line and load regulation, and low noise.
