Texas Instruments Voltage Regulator TO-220 5-Pin 300mV LM2991T/NOPB

Texas Instruments LM2991T/NOPB is an adjustable Low Dropout (LDO) linear voltage regulator designed for applications requiring efficient voltage regulation with negative polarity. Packaged in a TO-220 5-pin through hole mount, it provides reliable operation with a quiescent current of only 700μA, suitable for low noise power management.

This voltage regulator operates efficiently with a minimum input voltage down to -26V and a maximum input voltage of 300mV, making it ideal for circuits requiring precise voltage control and regulation. It supports operation in temperature environments up to 125°C, accommodating industrial and automotive electronic uses without compromise.

The compact 10.16mm length and 4.7mm width dimensions enable easy integration into densely packed electronic assemblies. The LM2991 series is well recognized for excellent line voltage regulation and high power supply rejection ratio (PSRR), suitable for reducing noise in sensitive analog and digital circuits.

Typical applications include power management ICs for industrial machinery, commercial electronics, and automotive electronics where stable voltage supply is critical. This device supports through hole mounting making it accessible for prototyping and repair.

Operates with low dropout voltage to maximize efficiency. Features low quiescent current minimizing power consumption. Handles operating temperatures up to 125°C for robustness. Compact TO-220 package with 5-pin configuration supports easy mounting.

High PSRR ensures clean voltage output for sensitive electronics.
