The LT1764AEQ-1.5#PBF is a low dropout (LDO) linear voltage regulator designed for fast transient response and low noise applications. It can supply up to 3A of output current with a typical dropout voltage of 340mV at 3A. The device operates with an input voltage range of 2.7V to 20V and provides a fixed 1.5V output.
Key electrical characteristics include a low quiescent current of 1mA, which drops to less than 1µA in shutdown mode. The regulator exhibits low output voltage noise (40µVRMS from 10Hz to 100kHz), making it suitable for sensitive RF power supplies. It is stable with output capacitors as low as 10µF, including ceramic types.
Internal protection features include reverse battery protection, current limiting, and thermal limiting. The LT1764AEQ-1.5#PBF is available in a surface-mount 5-DDPAK package (TO-263-6, D²Pak).
This regulator is ideal for 3.3V to 2.5V logic power supplies and can serve as a post-regulator for switching power supplies.
