Frequently Asked Questions
What is the dropout voltage of the LT1965ET-2.5#PBF at full load?
The LT1965ET-2.5#PBF has a typical dropout voltage of 310 mV and a maximum of 490 mV at 1.1 A output current, allowing it to regulate a fixed 2.5 V output from input voltages as low as 3.5 V, which is beneficial for battery-powered systems with tight headroom.
For which circuit designs is the LT1965ET-2.5#PBF particularly well suited due to its low noise?
The LT1965ET-2.5#PBF is well suited for RF local oscillators, precision ADC reference supplies, and audio preamplifiers where output noise must be minimized. Its low-noise LDO architecture combined with a 1.1 A output and 20 V maximum input rating supports sensitive analog designs operating from regulated 2.5 V rails.
What package does the LT1965ET-2.5#PBF use and how does it affect PCB layout for thermal management?
The LT1965ET-2.5#PBF is housed in a SOT-23-5 (5-pin) package with a maximum junction temperature of 125°C. At 1.1 A output, thermal resistance from junction to ambient must be managed with adequate copper pour, typically requiring at least 1 cm² of ground plane to stay within the safe operating area at full load.
