Linear Low Dropout (LDO) Regulator Solutions High Performance Analog ICs rrunm TECHNOLOGY

Linear Low Dropout (LDO) Regulator Solutions - 2

Introduction We offer a broad line of high performance low dropout (LDO) linear regulators with fast transient response, excellent line and load regulation, and very wide input voltage range from 0.9V to 100V. Output currents range from 20mA to 10A, with positive, negative and multiple output versions available. Many devices offer output voltage operation <0.8V and some feature operation as low as 0V, even with a single supply. Most are stable with ceramic output capacitors. Our PNP-based linear regulators offer reverse-input, reverse-output, and reverse-current protection. Our LDO+™...
