GENERAL DESCRIPTION
The LDO has an independent input and is capable of delivering up to 300mA. 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. The AAT2506 is available in either a fixed version with internal feedback or a programmable version with external feedback resistors. It can deliver 600mA of load current while maintaining a low 25µA no load quiescent current. The 1MHz switching frequency minimizes the size of external components while keeping switching losses low. The AAT2506 feedback and control delivers excellent load regulation and transient response with a small output inductor and capacitor. The AAT2506 is designed to maintain high efficiency throughout the operating range, which is critical for portable applications. The AAT2506 is available in a 12-pin TDFN33 package, and is rated over a temperature range of -40°C to +85°C.
