概要
Description
The LT1964ES5-BYP#TRMPBF is a low-dropout (LDO) voltage regulator designed by Analog Devices, formerly known as Linear Technology. It operates with a very low quiescent current, making it suitable for battery-powered applications. The device can deliver up to 200mA of output current with a dropout voltage of typically 0.34V at maximum load. Its key features include a wide input voltage range, typically from 1.8V to 20V, and low output noise, which is further reduced by an external bypass capacitor.
This regulator is equipped with internal protection features such as current limiting and thermal shutdown to prevent damage under fault conditions. It comes in a compact SOT-23 package, making it ideal for space-constrained applications. The "BYP" suffix indicates the presence of a bypass pin for further noise reduction, and the "#TRMPBF" refers to the part's packaging and RoHS compliance.
The LT1964ES5-BYP#TRMPBF is commonly used in applications requiring a stable and low-noise power supply, such as in precision analog circuits, RF systems, and portable devices.

Package
The LT1964ES5-BYP#TRMPBF is packaged in a SOT-23-5 form factor. This is a small-outline, transistor-style package with five leads, commonly used for surface-mount devices.
Pinout
The LT1964ES5-BYP#TRMPBF is a low-dropout (LDO) negative voltage regulator manufactured by Analog Devices. It comes in a 5-lead SOT-23 package. The five pins serve the following functions:
1. GND (Pin 1): Ground reference for the device.
2. IN (Pin 2): Input voltage pin where the unregulated negative input voltage is applied.
3. OUT (Pin 3): Output voltage pin that provides the regulated negative output voltage.
4. BYP (Pin 4): Bypass pin used to connect an external capacitor for noise reduction and improved transient response.
5. SHDN (Pin 5): Shutdown pin allows the regulator to be turned on or off. Connecting this pin to a low voltage turns the regulator off (shutdown mode), and a high voltage turns it on (active mode).
These pin functions make the LT1964ES5-BYP#TRMPBF suitable for applications requiring efficient power regulation with minimal noise and enhanced transient response in a compact package.
