TPS709 - Texas Instruments

TPS709 Voltage Regulators

The TPS709 series of linear regulators are ultralow, quiescent current devices designed for powersensitive applications. A precision band-gap and error amplifier provides 2% accuracy over temperature. Quiescent current of only 1 µA makes these devices ideal solutions for battery-powered, alwayson systems that require very little idle-state power dissipation.

Features

• Ultra-low IQ: 1 μA
• Reverse current protection
• Low ISHUTDOWN: 150 nA
• Input voltage range: 2.7 V to 30 V
• Supports 200-mA peak output
• 2% accuracy over temperature
• Available in fixed-output voltages: 1.2 V to 6.5 V
• Thermal shutdown and overcurrent protection
• Packages: SOT-23-5, WSON-6 2 Applications
