The LT1963AEQ-3.3#TRPBF is a 1.5A low dropout (LDO) linear voltage regulator from Analog Devices, designed for applications requiring fast transient response and low output noise. It provides a stable 3.3V fixed output voltage.
Key electrical specifications include an output current capability of 1.5A and a typical dropout voltage of 340mV at 1.5A. The device operates with a quiescent current of 1mA, which drops to less than 1µA in shutdown mode. It features low output noise of 40µVRMS (10Hz to 100kHz) and a PSRR of 63dB at 120Hz, making it suitable for sensitive RF applications.
Internal protection circuitry includes over current, over temperature, and reverse polarity protection. The regulator is stable with output capacitors as low as 10µF and is available in a surface mount 5-DDPAK package (TO-263-6, D²Pak).
This device is ideal for 3.3V to 2.5V logic power supplies and serves as a post regulator for switching supplies. Its robust design and performance characteristics make it a reliable choice for various power management needs.
