Figure 1. The UltraFast load transient response, 12 µV rms output noise, and 80 mV dropout voltage features of the dual-channel, 2.5 A LT3072 meet the needs of digital ICs with stringent power requirements. In this schematic, the three-state VO1B2–0 and VO2B2–0 pins are shown

Low dropout (LDO) linear regulators are often used to provide clean power to processor cores and communication circuits. In these applications, LDO regulators are used specifically because processors and power amplifiers have stringent performance requirements for power supply output noise and load transient re
