Texas Instruments LP2950CZ-5.0 Fixed LDO Voltage Regulator 5V 100mA TO-92

Texas Instruments LP2950CZ-5.0 LDO Voltage Regulator is a fixed 5V linear voltage regulator with a 100mA maximum output current and a 30V maximum input voltage. It suits designs that need a stable 5V supply with low quiescent current and low dropout voltage.

Overview

The LP2950CZ-5.0 is a 5V fixed output low-dropout (LDO) linear voltage regulator. It has a typical quiescent current of 75µA. The typical dropout voltage is 40mV at light loads and 380mV at the full 100mA output. Because quiescent current increases only minimally during dropout conditions, more of the supply power reaches the load, which can help prolong battery life in portable applications.

Key Features

The device has a typical initial output voltage tolerance of 0.5% and typical load and line regulation of 0.05%. Its output voltage temperature coefficient is very low, so it can also serve as a low-power voltage reference for sensitive circuits.

An error flag output gives a warning signal when the output voltage falls below a set threshold, which is a common indicator of depleting input batteries. This output can also be used to generate a power-on reset signal. A logic-compatible shutdown input allows the regulator to be switched on and off electronically.

The regulator requires only a minimum amount of capacitance for stable operation and remains stable with low-ESR output capacitors ranging from 10mΩ to 6Ω. Built-in current and thermal limiting protect the device under fault conditions. The device is manufactured without antimony or bromine (no Sb/Br).
