The LTC1844ES5-SD#TRPBF is a micropower, low noise, VLDO linear regulator designed by Analog Devices for low power and portable applications. It features a wide input voltage range from 1.6V to 6.5V and a very low dropout voltage, minimizing power loss.
Key electrical specifications include a low quiescent current of 35µA during normal operation, which drops to 10nA in shutdown mode. The regulator offers a typical output noise of 60µVRMS (10Hz to 100kHz) and ±1.75% voltage accuracy over temperature, voltage, and current ranges. It supports adjustable output voltages from 1.25V to 6V and also comes in fixed output voltage versions.
Protection features include output current limiting, short-circuit protection, and thermal overload protection. The device is stable with 1µF output capacitors, including ceramic types, and offers fast transient response. It is available in a low profile SOT-23-5 Thin package.
This regulator is well-suited for applications such as portable instruments, battery-powered systems, Bluetooth/802.11 cards, cellular phones, and PDAs.
