LMS1587IS-3.3 Description

Short technical summary and product information.

The Texas Instruments LMS1587IS-3.3 is a 3A, low dropout (LDO) linear voltage regulator. This specific variant provides a fixed 3.3V output voltage, making it suitable for applications requiring a stable power supply.

 

Key electrical specifications include a maximum input voltage of 13V and a minimum input voltage of 2.5V. It offers a maximum output current of 3A and a typical dropout voltage of 1150mV at 3A. The regulator features a typical quiescent current of 7mA and provides 72dB of PSRR at 120Hz. Protection features include over-current and over-temperature shutdown.

 

Packaged in a surface-mount DDPAK/TO-263-3 configuration, the LMS1587IS-3.3 is designed for efficient thermal management. Its operating temperature range is -40°C to 125°C, suitable for industrial applications. The device also offers adjustable output versions and is a direct replacement for LT 1585A/87.

 

This regulator is an excellent choice for low-voltage microprocessor applications where fast transient response and reliable power delivery are critical. Its fixed output simplifies design and reduces component count.
