The LT1963EQ-1.5 from LTC is a 1.5A low noise, fast transient response Linear Dropout (LDO) regulator. It is optimized for applications requiring quick response to load changes and minimal noise.
Key electrical specifications include an output current capability of 1.5A and a low dropout voltage of 340mV. The device exhibits very low output noise, measuring 40μVRMS from 10Hz to 100kHz, making it suitable for sensitive RF power supplies. It operates with a quiescent current of 1mA, which drops to less than 1μA in shutdown mode. The regulator is stable with output capacitors as small as 10μF.
Internal protection features include reverse battery protection, current limiting, and thermal limiting, eliminating the need for external protection diodes. The LT1963EQ-1.5 is available in fixed output voltages, including 1.5V, and also as an adjustable version. It is offered in TO-220, DD, SOT-223, and 8-lead SO packages, supporting various mounting requirements.
This LDO regulator is ideal for 3.3V to 2.5V logic power supplies and serves as a post-regulator for switching power supplies.
The LT1963EQ-1.5 can supply up to 1.5A of output current.
The dropout voltage for the LT1963EQ-1.5 is typically 340mV.
The LT1963EQ-1.5 has a low output noise of 40μVRMS from 10Hz to 100kHz.
The operating quiescent current is 1mA, and it drops to less than 1μA in shutdown.
