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

Texas Instruments LP2950CZ 5V 100mA Fixed LDO Voltage Regulator delivers a stable 5V fixed output in a compact through-hole TO-92 package, combining low quiescent current with low dropout voltage for efficient power regulation.

Overview

This high-precision, 5V fixed-output low-dropout (LDO) linear voltage regulator is engineered for efficiency and stability. It features a typical quiescent current of 75µA and a typical dropout voltage of 40mV at light loads, rising to 380mV at the full 100mA output current. Because the quiescent current increases only slightly even when the device is in dropout, it helps prolong battery life in portable applications.

Key Features

• Error flag output that warns when the output voltage falls below regulation
• Logic-compatible shutdown input for electronic on and off switching
• Current and thermal limiting protection
• Stable with low-ESR output capacitors from 10mΩ to 6Ω
• Requires minimal external capacitance for stability
• Green product, manufactured without antimony or brominated flame retardants

Accuracy and Performance

Careful design minimises error contributions. The device offers a tight initial output voltage tolerance (0.5% typical), load and line regulation of 0.05% (typical), and a very low output voltage temperature coefficient, which also makes it suitable for use as a low-power voltage reference.

Specifications

• Output voltage: 5V fixed
• Maximum input voltage: 30V
• Maximum output current: 100mA
• Dropout voltage: 380mV (typical) at 100mA
• Package: Compact, through-hole TO-92-3
