概要
Description
The LT1964ES5-SD is a low-noise, low-dropout (LDO) linear voltage regulator designed for applications requiring efficient power regulation. Manufactured by Analog Devices, this device is capable of delivering up to 200mA of output current with a dropout voltage of only 340mV at full load.
One of its key features is its ultra-low noise performance, with an output noise of just 30µV RMS over the 10Hz to 100kHz frequency range, making it ideal for sensitive analog circuits and RF applications. The LT1964ES5-SD also exhibits excellent transient response, and its stable output is achieved with a small ceramic capacitor as low as 2.2µF.
The regulator operates in a wide input voltage range from 1.8V to 20V, while the output voltage can be set externally from 1.22V to 19.5V. Additionally, it includes features such as current limiting, thermal shutdown, and reverse-battery protection to enhance reliability and safety.
Its compact SOT-23-5 package makes it suitable for space-constrained designs, making it a versatile choice for a variety of electronic applications.

Pinout
The LT1964ES5-SD is a low dropout (LDO) negative linear voltage regulator. It typically comes in a 5-lead SOT-23 package. Here's a brief overview of its pin count and functions:
1. Pin 1 (OUT): Output pin where the regulated negative voltage is provided.
2. Pin 2 (GND): Ground pin which serves as the reference point for the input and output voltages.
3. Pin 3 (SHDN): Shutdown pin used to turn the regulator on or off. Bringing this pin low enables the regulator, while bringing it high puts it in shutdown mode.
4. Pin 4 (IN): Input pin where the unregulated negative voltage is applied.
5. Pin 5 (NC): No Connection, typically not connected internally but used for mechanical support or thermal performance.
The LT1964ES5-SD is designed for applications requiring low noise and low dropout voltage, making it suitable for battery-powered devices, post-regulation applications, and powering analog circuits.
