The TPS27081ADDCR is a high-side Load Switch features industry-standard ESD protection on all pins providing better ESD compatibility with other on board components. The TPS27081A level shifts ON/OFF logic signal to VIN levels and supports as low as 1-V CPU or MCU logic to control higher voltage power supplies without requiring an external level-shifter. Switching a large value output capacitor CL through a fast ON/OFF logic signal may result in an excessive inrush current. To control the load inrush current, connect a resistor R2 and add an external capacitor C1 as shown in the Simplified Schematic in the Technical Data Sheet. To configure the TPS27081A to achieve a specific slew rate, refer to the Application and Implementation section. A single pull-up resistor R1 is required in standby power switch applications. In such applications connect the R2 pin of the TPS27081A to the system ground when inrush current control is not required.

• Adjustable turn-on and turnoff slew rate control through external R1, R2 and C1
• Supports a wide range of 1.2 to 8V supply inputs
• Integrated NMOS for PFET control
• Full ESD protection (all pins)
• Low ON-resistance, high-current PFET
• Ultralow leakage current in standby (typical 100nA)

The LT®6654 is a family of small precision voltage references that offers high accuracy, low noise, low drift, low dropout and low power. The LT6654 operates from voltages up to 36V and is fully specified from –55°C to 125°C. A buffered output ensures ±10mA of output drive with low output impedance and precise load regulation. These features, in combination, make the

LT6654 ideal for portable equipment, industrial sensing and control, and automotive applications. The LT6654 was designed with advanced manufacturing techniques and curvature compensation to provide 10ppm/°C temperature drift and 0.05% initial accuracy. Low thermal hysteresis ensures high accuracy and 1.6ppmP-P noise minimizes measurement uncertainty. Since the LT6654 can also sink current, it can operate as a low power negative voltage reference with the same precision as a positive reference.

The LT6654 references are offered in 6-lead SOT-23 package and an 8-lead LS8 package. The LS8 is a 5mm × 5mm surface mount hermetic package that provides outstanding stability.
