The TPS5420D is a High-output-current PWM Converter integrates a low resistance high side N-channel MOSFET. Included on the substrate with the listed features is a high performance voltage error amplifier that provides tight voltage regulation accuracy under transient conditions; an under-voltage-lockout circuit to prevent start-up until the input voltage reaches 5.5V, an internally set slow-start circuit to limit inrush currents and a voltage feed-forward circuit to improve the transient response. Using the ENA pin, shutdown supply current is reduced to 18µA typically. Other features include an active-high enable, over-current limiting, overvoltage protection and thermal shutdown. To reduce design complexity and external component count, the TPS5420 feedback loop is internally compensated.

Texas Instruments TPS27081ADDCR
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)

Texas Instruments TPS767D301PWP
The TPS767D301PWP is a Dual-output Low-dropout (LDO) Voltage Regulator that offers fast transient response, low dropout voltages, dual outputs and incorporating stability with 10µF low ESR output capacitors. The TPS767D301 dual voltage regulator is designed primarily for DSP applications. This device can be used in any mixed-output voltage application, with each regulator supporting up to 1A. Dual active-low reset signals allow resetting of core-logic and I/O separately. Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 85µA over the full range of output current, 0mA to 1A). These two key specifications yield a significant improvement in operating life for battery-powered systems.
- Dual output voltages for split-supply applications
- Output current range of 0mA to 1.0A per regulator
- 3.3/2.5, 3.3/1.8 and 3.3V/Adjustable output
- Fast-transient response
- 2% Tolerance over load and temperature
- 350mV Typical dropout voltage at 1A
- Ultra-low 85µA typical quiescent current
- 1µA Quiescent current during shutdown
