Package

The LT1965EDD#TRPBF is packaged in a 5-lead TSOT-23 (Thin Small Outline Transistor) package. This compact surface-mount package is designed for space-constrained applications.

Pinout

The LT1965EDD#TRPBF is a low dropout (LDO) linear voltage regulator with a pin count of 8. Its primary function is to provide a stable output voltage with low dropout voltage, making it suitable for applications requiring efficient power management.
The pin configuration is as follows:
1. Input (IN): Connection for the input voltage supply.
2. Ground (GND): Ground reference for the circuit.
3. Output (OUT): Regulated output voltage.
4. Bypass (BY): Connects to a capacitor to improve transient response.
5. Adjust (ADJ): Used to set the output voltage, typically for adjustable versions.
6. NC (No Connect): Not connected internally; can be left floating.
7. Thermal Pad: For heat dissipation, generally connected to ground (not a pin, but part of the package).
8. Compensation (COMP): For frequency compensation to stabilize the regulator.
This device is widely used in battery-powered applications due to its low quiescent current and high power supply rejection ratio (PSRR).
