The LP3963ES-3.3/NOPB is a 3.3V fixed output fast ultra-low-dropout (LDO) Linear Regulator operate from a 2.5 to 7V input supply. This device respond very fast to step changes in load which makes them suitable for low voltage microprocessor applications. The device is developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the device to operate under extremely low-dropout (LDO) conditions. The dropout voltage is typically 80mV at 300mA load current and 800mV at 3A load current.

• Low ground pin current
• 0.06% Load regulation
• 15µA Quiescent current in shutdown mode
• ±1.5% Output voltage accuracy
• ERROR flag indicates output status
• Minimum output capacitor requirements
• Overtemperature and overcurrent protection

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 VND600SP-E is a monolithic 2-channel high side Solid State Relay intended for driving resistive or inductive loads with one side connected to ground.
