SBVS186G MARCH 2012REVISED NOVEMBER 2015  
TPS709 150-mA, 30-V, 1-µA IQ Voltage Regulators with Enable  
1 Features  
3 Description  
The TPS709 series of linear regulators are ultralow,  
1
Ultralow IQ: 1 μA  
quiescent current devices designed for power-  
sensitive 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, always-on  
systems that require very little idle-state power  
dissipation. These devices have thermal-shutdown,  
current-limit, and reverse-current protections for  
added safety.  
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  
Shutdown mode is enabled by pulling the EN pin low.  
The shutdown current in this mode goes down to 150  
nA, typical.  
2 Applications  
The TPS709 series is available in WSON-6 and  
SOT-23-5 packages.  
Zigbee™ Networks  
Home Automation  
Metering
