LM20343MHE/NOPB  

DC Switching Voltage Regulators

The LM20343MHE/NOPB is a high-precision, low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. This device is designed to provide a stable and accurate output voltage to power sensitive electronic circuits, such as microcontrollers, analog-to-digital converters (ADCs), and digital signal processors (DSPs).

Description:

The LM20343MHE/NOPB is a fixed-output, low-dropout linear regulator with an output voltage range of 1.2V to 5.0V. It features a very low dropout voltage (typically 180mV at 1A load), which ensures high efficiency and stable output voltage even under heavy load conditions. The device is available in a small, thermally enhanced 10-lead MSOP package.

Features:

1. High precision output voltage: ±1% initial accuracy and ±2% over temperature.
2. Low dropout voltage: 180mV at 1A load (typical).
3. Low quiescent current: 70µA (typical).
4. Wide input voltage range: 2.5V to 5.5V.
5. Low output noise: 50µVRMS (typical).
6. High PSRR (Power Supply Rejection Ratio): 80dB at 1kHz.
7. Internal frequency compensation.
8. Thermal shutdown protection.
9. Enable/Disable control.
10. Small footprint: 10-lead MSOP package.

Applications:

1. Microcontroller power supplies.
2. Analog-to-digital converters (ADCs).
3. Digital signal processors (DSPs).
4. Radio frequency (RF) and wireless communication circuits.
5. Portable and battery-powered devices.
6. Telecommunication equipment.
7. Industrial and automotive electronics.
8. Any application requiring a stable and accurate voltage reference.

The LM20343MHE/NOPB is a reliable and efficient LDO regulator suitable for a wide range of applications where precise voltage regulation is essential. Its low dropout voltage, high precision, and small footprint make it an ideal choice for both low-power and high-current applications.
