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 TPS73701DCQ is a linear low-dropout (LDO) Voltage Regulator uses an NMOS pass element in a voltage-follower configuration. This topology is relatively insensitive to output capacitor value and ESR, allowing a wide variety of load configurations. Load transient response is excellent, even with a small 1µF ceramic output capacitor. The NMOS topology also allows very low dropout. This device uses an advanced BiCMOS process to yield high precision while delivering very low dropout voltages and low ground pin current. Current consumption, when not enabled, is less than 20nA and ideal for portable applications. This device is protected by thermal shutdown and fold-back current limit. It features reverse current blockage and freedom from output capacitor constraints. These features combined with an enable input makes the device ideal for portable applications.
