Positive Linear LDO Regulators

Analog Devices Inc. Positive Linear Low Dropout (LDO) Regulators are high-performance, low dropout linear regulators. The LDOs provide very low dropout, fast transient response, as well as excellent line and load regulation. These Positive Linear Regulators from Analog Devices also offer a very wide input voltage range from 0.9V to 80V. Output currents range from 100mA to 10A with positive and multiple outputs. The LDO regulators can be used in a wide range of applications.
