Linear & Switching Voltage Regulators

LP2951ACMM Description

The LP2951ACMM from Texas Instruments is a low-power, low-dropout (LDO) voltage regulator designed for precision voltage regulation in power-sensitive applications. This adjustable/fixed-output regulator supports an input voltage range up to 30V and delivers a 100mA output current with a low dropout voltage of 0.6V @ 100mA. Housed in an 8-VSSOP package, it features a quiescent current of just 120 µA, making it ideal for battery-operated systems. The device offers both adjustable (1.235V to 29V) and fixed 5V output options, providing flexibility for diverse design requirements.

LP2951ACMM Features

• Wide Input Range: Operates up to 30V, accommodating various power sources.
• Low Dropout Voltage: 0.6V @ 100mA ensures efficient operation even with small input-output differentials.
• Ultra-Low Quiescent Current: 120 µA minimizes power loss in standby modes.
• Enable Control: Integrated enable pin for power management and sequencing.
• Robust Protection: Includes over-current, over-temperature, and short-circuit protection for enhanced reliability.
• RoHS3 Compliant & REACH Unaffected: Meets environmental and regulatory standards.
• Surface-Mount Package: 8-VSSOP for compact PCB designs.

LP2951ACMM Applications

The LP2951ACMM excels in applications requiring stable, low-noise voltage regulation with minimal power dissipation:
