AAT2506 Datasheet | AAT

Description The AAT2506 is a member of Analogic Tech's Total Power Management IC™ (TPMIC™) product family. It is a low dropout (LDO) linear regulator and a step-down converter with an input voltage range of 2.7V to 5.5V, making it ideal for applications with single lithium-ion/polymer batteries. The LDO has an independent input and is capable of delivering up to 300m A. The linear regulator has been designed for high-speed turn-on and turn-off performance, fast transient response, and good power supply rejection ratio (PSRR). Other features include low quiescent current and a low dropout voltage. Features - - - - - - - - - - - - - - - - - - Sys Pwr™ The AAT2506 is available in either a fixed version with internal feedback or a programmable version with external feedback resistors. It can deliver 600m A of load current while maintaining a low 25µA no load quiescent current. The 1MHz switching frequency minimizes the size of external ponents while keeping switching losses low. The AAT2506 feedback and control delivers excellent .. load regulation and transient response with a small Applications output inductor and capacitor. - Cellular Phones The AAT2506 is designed to maintain high efficien- Digital Cameras cy throughout the operating range, which is critical - Handheld Instruments for portable applications. - Microprocessor/DSP Core/IO Power The AAT2506 is available in a 12-pin TDFN33 - PDAs and Handheld puters package, and is rated over a temperature range of - Portable Media Players -40°C to +85°C.
