The TPS2551QDBVRQ1 is a Power Distribution Switch intended for applications in which heavy capacitive loads and short circuits are likely to be encountered. The current-limit threshold is user adjustable between 100mA and 1.1A via an external resistor. The power-switch rise and fall times are controlled to minimize current surges during switching. The device limits the output current to a desired level by switching into a constant-current mode when the output load exceeds the current-limit threshold or a short is present. An internal reverse-voltage detection comparator disables the power-switch in the event that the output voltage is driven higher than the input to protect devices on the input side of the switch. The FAULT logic output asserts low during both overcurrent and reverse-voltage conditions.

Texas Instruments LP3963ES-3.3/NOPB
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.

Texas Instruments LM338T/NOPB
The LM338T/NOPB is an adjustable 3-terminal positive Voltage Regulator, capable of supplying in excess of 5A over a 1.2 to 32V output range. They are exceptionally easy to use and require only 2 resistors to set the output voltage. Careful circuit design has resulted in outstanding load and line regulation-comparable to many commercial power supplies. A unique feature of the LM338T/NOPB family is time-dependent current limiting. The current limit circuitry allows peak currents of up to 12A to be drawn from the regulator for short periods of time. This allows the LM338T/NOPB to be used with heavy transient loads and speeds start-up under full-load conditions. Under sustained loading conditions, the current limit decreases to a safe value protecting the regulator.

Texas Instruments LP38855S-1.2
The LP38855S-1.2 is a 1.8V fixed output fast-response high-accuracy low-dropout (LDO) Linear Regulator with Enable. The device can maintain output voltage regulation with an extremely low input to output voltage drop. Fabricated on a CMOS process, the device operates from two input voltages, VBIAS provides power for the internal bias and control circuits, as well as drive for the gate of the N-MOS power transistor, while VIN supplies power to the load. The use of an external bias rail allows the part to operate from ultra-low VIN voltages. Unlike bipolar regulators, the CMOS architecture consumes extremely low quiescent current at any output load current. The use of an N-MOS power transistor results in wide bandwidth, yet minimum external capacitance is required to maintain loop stability. The fast transient response of this device makes it suitable for use in powering DSP, microcontroller core voltages and switch mode power supply post regulators.
- Stable with 10µF ceramic capacitors
- ±1.0% Precision output voltage across all line and load conditions (TJ = 25°C)
