LT1764EQTRPBF Description

Short technical summary and product information.

The LT1764EQTRPBF is a low dropout (LDO) linear voltage regulator from Linear Technology, designed for applications requiring fast transient response and low noise. It can supply up to 3A of output current with a typical dropout voltage of 340mV at 3A.

This regulator features a wide input voltage range from 2.7V to 20V and offers fixed output voltages of 1.5V, 1.8V, 2.5V, and 3.3V, as well as an adjustable output option from 1.21V to 20V. The quiescent current is 1mA during normal operation and drops to less than 1µA in shutdown mode. Its low output voltage noise of 40µVRMS (10Hz to 100kHz) makes it suitable for sensitive RF applications.

Internal protection circuitry includes reverse battery protection, current limiting, and thermal limiting. The LT1764 series is available in TO-220, DD, and 16-lead TSSOP packages, supporting through-hole and surface-mount designs. It is stable with output capacitors as low as 10µF.
