Product Description
Texas Instruments LM2937ET-3.3/NOPB is a low dropout (LDO) linear voltage regulator designed for stable power regulation in a variety of electronic circuits. This regulator uses a TO-220 3-pin package, supporting through-hole mounting to ensure robust assembly on printed circuit boards. Operating with a maximum input voltage of 26V and a minimum input of 4.75V, it ensures smooth voltage regulation to downstream components.
The device features a quiescent current of only 20mA, which improves efficiency and reduces power consumption in applications where energy optimization is critical. It supports positive polarity, making it compatible with common positive voltage circuits.
With compact physical dimensions (length of 10.16mm, width of 4.7mm, and height of 8.89mm), the LM2937ET regulator easily fits in tight spaces typical of modern electronic designs. It is rated for operation up to 125°C, providing dependable performance even in industrial environments with elevated ambient temperatures.
The LM2937 series is engineered to have low dropout voltage, excellent line voltage regulation, and high power supply rejection ratio (PSRR), making it suitable for precision applications that require clean and steady power supply. This regulator does not carry specific automotive standard approvals but can be used in non-automotive industrial and consumer electronics.
This voltage regulator from Texas Instruments is ideal for electronics manufacturers and engineers designing power management circuits for industrial, consumer, and commercial electronic equipment. The through-hole mount package TO-220 type allows easy replacement and prototyping on through-hole PCB layouts.
Features low quiescent current (20mA) for efficient power consumption. Positive polarity and through-hole TO-220 package for robust mounting. Compact dimensions suitable for space-constrained PCB layouts. High reliability up to 125°C operating temperature.
Excellent line regulation and PSRR for clean voltage output. Supports a broad input voltage range from 4.75V to 26V. Ideal for industrial and general-purpose electronic devices. Part of Texas Instruments LM2937 linear regulator family.
