Noise Sensitive Applications Want Ultralow Noise LDO Regulators

Amit P. Patel, Senior Design Engineer, Power Products & Steve Knoth, Senior Product Marketing Engineer – Power Products, Linear Technology Corporation

Linear Regulators are integrated circuits that step a voltage down from a higher voltage to a lower voltage without the need of an inductor. The low dropout linear regulator (LDO) is a special type of linear regulator in which the dropout voltage – the differential between the input-to-output voltages needed to
