Product Overview
The TPS706 is a Texas Instruments 150-mA low-IQ LDO regulator in the Power_Management category. It is specified for a 2.7 to 6.5 V input range and fixed regulated outputs from 1.2 to 5.0 V, with recommended output current from 0 to 150 mA and peak output current support of 200 mA.
Electrical behavior includes 1 uA quiescent current, 1.3 uA typical ground pin current at no load for VOUT up to 3.3 V, and 350 uA typical ground pin current at 150 mA. The device provides -2% to +2% DC output accuracy for VOUT below 3.3 V over -40°C to 125°C, and -1% to +1% accuracy for VOUT at or above 3.3 V over -40°C to 85°C.
Package choices include SOT-23-5, 2.90 mm x 1.60 mm, and WSON-6, 2.00 mm x 2.00 mm. The OUT pin requires a 2.2-uF or greater ceramic capacitor to ground for stability, with a recommended output capacitance range of 2 uF to 47 uF. Applications include enable-controlled regulated rails, 150-mA fixed-voltage supplies, and low-current shutdown power paths.

Procurement Notes
When requesting a quote for TPS706, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For power IC and power device sourcing, voltage rating, current rating, power dissipation, package thermal performance, protection features, qualification grade and application conditions should be reviewed before approval.
FAQ
What input voltage range does the TPS706 support?
The TPS706 is specified for a recommended input voltage range of 2.7 to 6.5 V. Absolute maximum voltage ratings for IN, EN, and OUT are -0.3 to 7 V with respect to GND.
What output current is supported by the TPS706?
The recommended operating output current range is 0 to 150 mA. The feature summary lists 200 mA peak output current support, and the output current limit is specified as 200 mA minimum, 320 mA typical, and 500 mA maximum.
What capacitors are specified for TPS706 operation?
The extracted facts list 0 to 1 uF recommended input capacitance, with 2.2 uF used in the typical application. The output capacitor range is 2 uF minimum, 2.2 uF nominal, and 47 uF maximum.
How does the TPS706 enable pin operate?
The EN pin is an enable input. A high level enables the device, while a low level places it in low-current shutdown. The device may be left floating to enable, and maximum EN voltage must remain below 6.5 V.
